1.1 Warning signs used

CAUTION Warning of personal injury. Slight reversible injuries may result. 2 Safety instructions

• Read this document prior to set-up of the unit. Ensure that the product is suit- able for your application without any restrictions.

• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property can occur.

• Improper or non-intended use may lead to malfunctions of the unit or to un- wanted effects in your application. That is why installation, electrical connec- tion, set-up, operation and maintenance of the unit must only be carried out by qualified personnel authorised by the machine operator.

• In order to guarantee the correct condition of the device for the operating time it is necessary to use the device only for media to which the wetted materials are sufficiently resistant (→ Technical data).

• The responsibility whether the measurement devices are suitable for the respective application lies with the operator. The manufacturer assumes no liability for consequences of misuse by the operator. Improper installation and use of the devices result in a loss of the warranty claims.

• For medium temperatures above 50 °C (122 °F) some parts of the housing can heat up to over 65 °C (149 °F). Moreover, during installation or in case of a fault5

(e.g. housing damage) media under high pressure or hot media can leak from the system. To avoid personal injury, take the following measures: ► Install the unit according to the applicable rules and regulations. ► Ensure that the system is free of pressure during installation. ► Protect the housing against contact with flammable substances and unintentional contact. To do so, equip the unit with suitable protection (e.g. protective cover). ► Do not press the pushbuttons manually; instead use another object (e.g. ballpoint pen). 3 Functions and features Pressure Equipment Directive (PED): The units comply with section 3, article 3 of the Directive 97/23/EC and must be designed and manufactured for non-super- heated liquids of group 2 fluids in accordance with the sound engineering practice. The unit monitors liquid media. It detects the two process categories volumetric flow and medium temperature. Application area

• Low viscosity oils (viscosity: 7...40 mm²/s at 40 °C / 7...40 cSt at 104 °F)

• High viscosity oils (viscosity: 30...68 mm²/s at 40 °C / 30...68 cSt at 104 °F) Selection of the medium to be monitored → 10.4.9.6 4 Function

4.1 Process measured signals

The unit displays the current process values. It generates 2 output signals according to the parameter setting. OUT1: Parameter setting - Switching signal for volumetric flow quantity limit value (→ 10.2.1) OUT2: 2 selection options Parameter setting - Switching signal for volumetric flow quantity limit value (→ 10.2.2) - or switching signal for temperature limit value (→ 10.3.1)

4.2 Volumetric flow monitoring

The volumetric flow is monitored by an ultrasonic measuring system, the meas- ured signals are evaluated by the electronics. 2 switching signals for volumetric flow limit values can be provided (output 1 and output 2). On the switching functions → 4.4.

4.3 Temperature monitoring

OUTx changes its switching status if it is above or below the set switching limits (SPx, rPx). The following switching functions can be selected:

Normally open: [OUx] = [Hno] Normally closed: [OUx] = [Hnc] First the set point (SPx) is set, then the reset point (rPx) with the requested difference. When SPx is adjusted, rPx is changed automatically; the dif- ference remains constant. Example of volumetric flow monitoring HY = hysteresis

FE FE Fnc Fno Normally open: [OUx] = [Fno] Normally closed: [OUx] = [Fnc] The width of the window can be set by means of the difference between SPx and rPx. SPx = upper value rPx = lower value. Example of volumetric flow monitoring FE = window When set to the window function the set and reset points have a fixed hys- teresis of 0.25 % of the final value of the measuring range. This keeps the switching status of the output stable if the volumetric flow varies slightly.8

Start-up delay The start-up delay dST influences the switching outputs of the volumetric flow monitoring. If the start-up delay is active (dST > 0), note: as soon as the volumetric flow exceeds 0.5 % of the final value of the measuring range, the following processes are carried out: > The start-up delay is activated. > The outputs switch as programmed: ON for NO function, OFF for NC function. After the start of the start-up delay there are 3 options:

1. The volumetric flow increases quickly and reaches the set point / good range

within dSt. > Outputs remain active.

2. The volumetric flow increases slowly and does not reach the set point /good

range within dST. > Outputs are reset.

3. Volumetric flow quantity falls below 0.5 % of the final value of the measuring

range within [dSt]. > Outputs are reset at once; dST is stopped. Example: dSt for hysteresis function9

Volumetric flow quantity Q reaches 0.5 % of VMR dST starts, output becomes active 2 dST elapsed, Q reached SP Output remains active 3 Q below SP but above rP Output remains active 4 Q below rP Output is reset 5 Q reaches again 0.5 % of VMR dST starts, output becomes active 6 dST elapsed, Q has not reached SP Output is reset 7 Q reaches SP Output becomes active Example: dSt for window function Condition Reaction 1 Volumetric flow quantity Q reaches 0.5 % of VMR dST starts, output becomes active. 2 dST elapsed, Q reached good range Output remains active 3 Q above SP (leaves good range) Output is reset 4 Q again below SP Output becomes active again 5 Q below rP (leaves good range) Output is reset again 6 Q reaches again 0.5 % of VMR dST starts, output becomes active 7 dST elapsed, Q has not reached good range Output is reset 8 Q reaches good range Output becomes active10

4.6 Customer-specific calibration (CGA)

The customer-specific calibration allows changing the gradient of the curve of measured values (→ 10.4.4). It influences the display and the outputs. 140 % MEW 100 % MEW 60 % MEW MEW Q

A = operating value for display and output signals Q = flow MEW = final value of the measuring range V0 = curve of measured values with factory setting V1, V2 = curve of measured values after calibration The change in the gradient is indicated in per cent. Factory setting = 100 %. After a change the calibration can be reset to factory setting (→ 10.4.5).11

5 Installation ► Avoid deposits, accumulated gas and air in the pipe system.

5.1 Recommended mounting position

► Install the unit in that section of the plant where the medium flows under pres- sure. This avoids disturbance by air bubbles. ► Install the unit so that the measuring pipe is completely filled. ► Arrange for inlet and outlet pipe lengths. Disturbances caused by bends, valves, reductions, etc. are compensated for. It applies in particular: No shut-off and control devices are allowed directly in front of the unit. 5 x D

S = disturbance D = pipe diameter F = flow direction ► Install in front of or in a rising pipe.

► Avoid the following installation positions:

Directly in front of a falling pipe. In a falling pipe.

At the highest point of the pipe system. Directly in front of the spout of the pipe.

On the suction side of a pump. Flow rate direction horizontal, unit vertical, connector upwards. F = flow direction13

5.3 Installation in pipes

The unit can be installed in pipes using adapters. Information about the available adapters at www.ifm.com.

1. Screw the adapter (B) into the pipe (A).

2. Place the seals (C) and install the unit according to the marked flow direction.

► To mount the adapters on the process connection of the sensor use suitable lubricants.

3. Screw the adapter (B) with the threads (D) until it is hand-tight.
