5.2 Function

Function overview

The OVEM-LK is a vacuum generator with digital transmission of setpoint and actual value as well as diagnostics and parameterisation options. Communication takes place in IO-Link mode. SIO mode is supported.

– IO-Link parameters and functions in accordance with Smart Sensor profiles
- 2 binary data channels for programming switching functions and switching characteristics.

i

SIO mode: local configuration via the operating buttons. In the SIO mode, OVEM has the function of a 2P variant (1 switching input, 2 switching outputs).

• Control of the compressed air supply with 2 valve functions 5.2.2 Valve control
• Auto-drop function: generation of an automatic ejector pulse/power ejector pulse for accelerated vacuum purging and safe set-down 5.2.2 Valve control
  – Air saving function → 5.2.3 Air saving function
  – Electrical and mechanical manual override
• → 9.1 Mechanical manual override
• → 9.2 Electrical manual override

- Monitoring of vacuum build-up by integrated pressure sensor. If the setpoint value is reached, or if it is not reached due to malfunctions (e.g. leakage, dropped workpiece), the vacuum generator sends an electrical signal and a status message.

- Internal check valve prevents vacuum purging if vacuum generation is interrupted.

– Data storage and expanded monitoring function.

5.2.1 Switching functions

The binary outputs can be configured via the switching functions. The switching status information is thereby made available at the electrical connection as a process value or binary signal.

- IO-Link mode: 3 BDC (binary data channels), bit 0: BDC1 or BDC2, bit 1: BDC3

→ 14.1.3 Process data

– SIO mode: 2 switching outputs Out A and Out B

The switching logic of the binary outputs can be configured as normally open (N/O contact) or normally closed (N/C contact). The switching mode of the binary outputs can be specified as threshold value or window comparators.

Threshold value comparator Normally open (N/O contact) Normally closed (N/C contact)

Switching function:– 1 switching point (SP1)TEACH mode1):– 2 teach points (TP1, TP2)– SP1 = 1/2 (TP1+TP2)

1) TP1 = minimum pressure value, TP2 = maximum pressure value, independent of the teach-in sequence
Tab. 6 Threshold value comparator: setting of switching point SP1 and hysteresis HY

Window comparator Normally open (N/O contact) Normally closed (N/C contact)

Switching function:– 2 switching points (SP1, SP2)TEACH mode ^1) :– 2 teach points (TP1, TP2)

1) TP1 = minimum pressure value, TP2 = maximum pressure value, independent of the teach-in sequence
Tab. 7 Window comparator: setting of switching points SP1, SP2 and hysteresis HY

5.2.2 Valve control

The vacuum solenoid valve or the ejector pulse solenoid valve is controlled as defined by the input signal.

Product overview

• IO-Link mode: 2 BCS (binary control signals), bit 0: BCS1, bit 1: BCS2 → 14.1.3 Process data
• SIO mode: 1 switching input DI1 ( BCS1). Switching input positive switching (PNP)

Control of the ejector pulse

- Auto-drop function

The ejector pulse is generated after the “Suction” signal change (BCS1).

The pulse length can be set by the "Auto-drop time" parameter Tab. 27 Device parameters

i

Destruction of the vacuum sensor due to overpressure (-CPE/-OPE)

The exhaust duct is sealed tightly during the power ejector pulse. This can cause overpressure at the vacuum port and destroy the vacuum sensor.

- Use power ejector pulse only in open vacuum systems.

5.2.3 Air saving function

The air saving function reduces air consumption during the evacuation phase.

Product overview

1 Hysteresis
3 Threshold value "Switch on suction"
2 Threshold value "Switch off suction" = switching point SP_A1
4 Ejector pulse

Fig. 4 Mode of operation of the air saving function

If the pressure value has reached switching point SP1 2, vacuum generation is deactivated. An internal check valve prevents reduction of the vacuum. Vacuum can still be reduced slowly due to leakage in the overall system (e.g. due to rough workpiece surfaces). To reduce power consumption, vacuum generation is not switched on until it falls below the lower threshold value 3.

The air saving function is activated in the factory.

If air-permeable workpieces are transported, the vacuum is reduced more quickly, which would cause the vacuum generation to switch unnecessarily often. In this case, it makes sense to deactivate the air saving function.

5.2.4 Monitoring and diagnostics

The vacuum generator has monitoring functions that enable early detection of malfunctions or faults during operation.

- Monitoring of process parameters (pressure value at the vacuum connection, switching points, switching outputs and switching inputs, evacuation time t_E , pressurisation time t_B and critical limit values)

- Diagnostic messages 11.2 Diagnostic levels

– Fault detection → 11 Fault clearance

The monitoring functions are activated at the factory (except monitoring of the evacuation and pressurisation times). The time monitoring can be activated through setting of the critical limit values SP1 (evacuation time) and SP2 (pressurisation time) in BDC4 → Tab. 26 Smart Sensor profile parameters

i

The switching status information of the BDC4 is not included in the process input data (Process data IN).

5.2.5 Measured variables

Pressure value (vacuum)

The pressure value (vacuum) between the vacuum port and filter is continuously measured.

i

In the OVEM-...-20/30-C, the pressure value (vacuum) between the filter and the check valve is continuously monitored.

The minimum and maximum measured pressure values are saved. If the operating voltage of the vacuum generator is switched off, these values are reset.

Cycle time

A cycle covers the time from the start of evacuation through ejection to the start of the new evacuation.

Evacuation time and pressurisation time

The evacuation time t_E is measured from the start of evacuation until reaching of the switching point SP1 by BDC1 or BDC2.

The pressurisation time t_B is measured from the start of pressurisation to the time at which the pressure value (vacuum) falls below -50 mbar.

Product overview

1 Switching point SP1 (BDC1 or BDC2)
tE Evacuation time
2 Reset point RSP1 (BDC1 or BDC2)
tB Pressurisation time

Fig. 5 Cycle time - example for Out A (air save)

5.2.6 Teach function

The Teach function enables configuration of the switching points and time monitoring during runtime.

Static teach-in

Depending on the Teach command, one switching point (SP) or 2 switching points (SP1, SP2) are determined from 2 teach points. The switching points are determined statically, that is, the measurement value remains constant during the entire teach-in procedure. The air saving function is deactivated during execution of the teach-in procedure.

- Teach commands Tab. 32 Command code

- Simplified Teach commands "BDCx Start" (Start Teach), "BDCx Stop" (Stop Teach) can be used independently of the switching function. The sequence of the teach points need not be considered.

- For all commands, the desired channel must first be selected.

Dynamic teach-in

Setpoint values are calculated within the teach-in procedure from a time period. The procedure is used to determine evacuation and air supply times. Fig.6

After the start of the teach-in, time t_E and t_B are measured at every cycle. The times are averaged over multiple cycle times. At the end of the teach-in, a function reserve of 100% is added to the averaged values.

1 Transport time

4 Cycle time 2

2 Return time

5 Cycle time N

3 Cycle time 1

Fig. 6 Dynamic teach-in mode of operation

5.2.7 Data storage

The data storage mechanism (DS) permits consistent and updated saving of device parameters to higher levels, such as PLC programs or fieldbuses. The vacuum generator sends changes to the parameters to the IO-Link Master, which receives the parameter, saves it in a higher-order system and can make it available to the new device if the vacuum generator is replaced.

- Parameters that can be saved 14.1 Technical data for parameterisation interface

- The data storage mechanism is supported at the device, but is administered by the application (IO-Link Master).

5.2.8 Block parameterisation

Block parameterisation permits uniform access to parameters over multiple indexes or subindexes as well as transfer of entire parameter sets.

- Transfer of block parameters by start and end commands Tab. 32 Command code

- Parameter changes (e.g. through teach-in) are blocked during the transfer.

– In case of an invalid parameter set, the changed parameters are discarded and the previous parameter set is reactivated.

5.2.9 Operating statuses and menu structure

8 Commissioning

i

Commissioning by qualified personnel.

8.1 Commissioning the vacuum generator

At initial commissioning, the vacuum generator is placed in operation with the factory settings.

Requirement

Vacuum generator is fully mounted and connected 6 Assembly.

Checking operating conditions

- Check operating conditions and critical limits 14 Technical data.

Commissioning the vacuum generator OVEM-...-OE/-OPE

1. Apply operating pressure to supply port (1).
   Negative pressure is generated at the vacuum port (2).
2. Switch on the operating voltage.
   The current pressure is displayed and the vacuum generator is ready for operation.

Commissioning the vacuum generator OVEM-...-CE/-CPE

1. Apply operating pressure to supply port (1).
2. Switch on the operating voltage.
3. Activate suction: apply input signal to pin 5.

Negative pressure is generated at the vacuum port (2). The current pressure is displayed and the vacuum generator is ready for operation.

Changing the operating pressure changes the power of the negative pressure at the vacuum port. This allows the vacuum to be adjusted.

Functions and parameters can be specified:

• manually at the device EDIT mode
  -by teach-in TEACH mode
  -by teach-in TEACH mode

8.2 Setting the intensity of the ejector pulse

Technical diagram showing a mechanical component with a close-up view of its connection to a door panel (no text or symbols present)

Fig. 14 Set the intensity of the ejector pulse

– Vacuum generator is in operation

Procedure

1. Completely screw in flow control screw for regulation of the ejector pulse.

2. Switch on vacuum generation.

Negative pressure is generated at the vacuum port (2).

1. Switch off vacuum generation.

2. Switch on solenoid valve for ejector pulse.

An ejector pulse is not generated.

1. Switch off solenoid valve for ejector pulse.

2. Slightly unscrew the flow control screw to regulate the ejector pulse.

3. Switch on solenoid valve for ejector pulse.

An ejector pulse is generated.

1. Repeat steps 1 to 7 until the required intensity of the ejector pulse is set.

i

The use of large suction cups with connectors can create a device-independent vacuum due to the interference resistance when the suction cup with connector is detached from the workpiece.

Set up the ejector pulse accordingly.
