The operating instructions
... apply to all control monitors of type A 300. There are the following differences between the individual units:
- Rating of the permissible AC or AC/DC supply which is indicated on the type label of the unit.
- Setting range (pulses/min), indicated on the type label.
• Additional transistor output, indicated on the wiring label.
... are part of the unit. They contain information about the correct handling of the product. Read them before use to get familiar with operating conditions, mounting and operation. Adhere to the safety instructions. The operating instructions are made for authorised persons according to the EMC and low voltage guidelines.
1. Safety instructions
Follow the operating instructions, as failure to do so may result in damage to both the unit and persons using the equipment.
Ensure that the unit is isolated from any supply voltages before installing or changing the equipment. Installation should only be carried out by qualified personnel (due to the IP20 rating). When altering the settings of the units please ensure that the unit is not connected to the monitored plant.
The design of the units corresponds to protection class II except for the terminal blocks where protection against accidental contact (safety from finger-touch to IP20) for operation by qualified staff is only guaranteed if the terminal screw has been completely screwed in. The unit has to be mounted in a housing (protection rating IP20 or higher) which can only be opened using a tool or in a locked control cabinet.
If the unit has an external 24 V DC supply, this voltage has to be generated and supplied externally according to the requirements for safe extra-low voltage (SELV) since without further measures this voltage is supplied near the operating elements and at the terminals for the supply of connected pulse pick-ups.
The wiring of all signals concerning the SELV circuit of the unit must also meet the SELV criteria (safe extra-low voltage, safe galvanic separation from other circuits).
If the externally supplied or internally generated SELV voltage has an external connection to ground (SELV becomes PELV), the responsibility lies with the user in the framework of the respective applicable national regulations for installation. All statements in the operating instructions refer to SELV voltage which is not grounded.
According to the technical specifications below the unit can be operated in a wide operating temperature range. Because of the additional internal heating the operating elements and the housing walls can have high perceptible temperatures when touched in hot environments.
In case of malfunctioning of the unit or uncertainties please contact the manufacturer. An unauthorised access of the unit can lead to considerable risks for the safety of persons and plant. It is not permitted and leads to an exclusion of liability and warranty.
2. Function and features
The A300 is a pulse evaluation system for monitoring underspeed/standstill. It receives pulses from external sensors, measures the pulse interval and calculates the input frequency (=actual value), compares it with the preset switch point (preset value) and switches the output in accordance with the preset parameters.
- Setting range: see type label (standard values: 5...25 and 20...100 pulses/min).
- Maximum input frequency: as standard 15,000 pulses/min (which corresponds to 250 Hz).
Special versions: DA0025 (4.5 kHz), DA0038 (1.6 kHz), DA0200 (200 Hz). If this value is exceeded, the A 300 switches as for input frequency = 0.
• Minimum pulse length: 2ms.
- Pulse pick-ups: 3-wire DC PNP, 2-wire AC/DC, 2-wire quadronorm, incremental encoders, mechanical switches.
Signal level for the A 300 pulse input: minimum 14 V.
The monitor is not approved for safety tasks in the field of safety of persons.
3. Mounting
Mount the unit in a control cabinet with a protection rating of at least IP 54 to guarantee protection against accidental contact with voltages and against atmospheric influence. The control cabinet should be installed in accordance with local and national rules and regulations.
Mount the unit on a DIN rail or by means of a mounting base. Once mounted leave enough space between the unit and the top and bottom of the control cabinet (to enable air circulation and to avoid excessive heating).
Mounting of the pulse pick-ups:
Adhere to the mounting instructions of the manufacturer.
For optimum functioning of inductive switches the following dimensions should be adhered to:
• B = 2 × A
• C = 12 × S_n
4. Electrical connection
The unit must only be connected by an electrician.
The national and international regulations for the installation of electrical equipment must be observed.
Avoid contact with voltages.
Disconnect the plant from power before wiring. Check if the relays are connected to voltages of external power supplies.
Observe the usual ESD protection measures.
In order to avoid malfunction caused by interference, lay the sensor cable separately from the load cable. Max. length of the sensor cable: 500m.
Terminal connection:
| A 300 with switched-mode power supply | A 300 with transformer power supply |
 |  |
 |  |
Power supply
Power supply either
- at terminals 15 and 16 (AC/DC; for A 300 with switched-mode power supply; AC for A 300 with transformer power supply)
• or at terminals 6 and 7 (24 V DC).
For DC units the supply voltage must be protected externally.
The terminals of the DC supply are directly linked with the terminals of the pulse pick-up supply. This is why the SELV criteria must be adhered to for DC supply (protective low voltage, circuit galvanically separated from other circuits, not earthed).
If the DC circuit is to be earthed (e.g. because of national regulations), the PELV criteria have to be adhered to (protective low voltage, circuit galvanically separated from other circuits).
If the unit is supplied with AC voltage, the low voltage supply for the pulse pick-up meets the SELV criteria.
The device shall be supplied from an isolating source and protected by an overcurrent protection device such that the limited voltage circuit requirements in accordance with UL 508 are met.
Connection of pulse pick-ups
A 300 provides approx. 24V DC (max. 30 mA) for the supply of pulse pick-ups. Pulse pick-ups which need higher voltage/higher current consumption must have an external supply. In this case the reference point of the external voltage must be connected to terminal 6; the positive pole of the external power supply must not be connected with the A 300.
Please also adhere to the SELV criteria for the pulse pick-up connection so that there is no dangerous contact voltage at the sensor which can enter the unit!

5. Setting
5. 1. Selection of the switching function and setting range
Selection is done with switch (5), there are 4 functions:
| switching function | setting range | switch position |
| Operating state: minimum rotational speed reached / standstill | 5...25 pulses/min. | I |
| The output relay energises when the input frequency (pulses/min) becomes lower than the set switch point (SP). If the input frequency becomes higher again, the relay switches back at the switch point + hysteresis (SP+Hy). | 20...100 pulses/min. | IV |
| The output relay is de-energised during the start-up delay and as long as the input frequency is higher than the set switch point. | ||
| Fault state: below minimum rotational speed | 5...25 pulses/min. | II |
| The output relay de-energises when the input frequency (pulses/min) becomes lower than the set switch point (SP). If the input frequency becomes higher again, the relay switches back at the switch point + hysteresis (SP+Hy). | 20...100 pulses/min. | III |
| The output relay is energised during the start-up delay and as long as the input frequency is higher than the set switch point.. |
Relay energised = transistor output conductive, relay de-energised = transistor output blocked.
5.2. Setting of the switch point
Set the switch point with pot (1).
For low switch points the A 300 recognises changes of the actual value only after a reaction time (which depends on the interval between two successive pulses). This particularly applies to the switching functions I and II. For these functions the reaction time is about 12s in case of a switch point of 5 pulses/min and about 1.2s in case of a switch point of 50 pulses/min.
5. 3. Hysteresis
The hysteresis determines the difference between switch-on point and switch-off point (switch-on point = the output changes its switching state, switch-off point = the output switches back to the previous state).
The hysteresis is set to the factor 1.05 (which corresponds to 5% of the switch point).
With unequal distances between cams different times between two successive pulses are measured. They can be above or below the switch point so that the output continuously changes its switching state. By increasing the hysteresis factor this can be prevented.
5.4. Start-up delay
The start-up delay suppresses an error signal as long as the machine is in the process of starting and has not yet reached its nominal speed.
- It is set to 15 s but can be reduced by a resistor between the terminals 1 and 2.
Resistor values: between 100 k (which corresponds to 2 s) and 3.9 M (which corresponds to 14 s).
- After application of the operating voltage the start-up delay is active only once. If the drive is often turned on and off, couple the supply voltage of the drive and the monitor. By doing so, the start-up delay is active every time the drive is turned on.

| Outputs |
| Output relaySwitching capacity: max. 250V AC, 4 A. The current has to be limited to these values by appropriate external measures. For inductive loads the relays must be subjected to external interference suppression.The relay contacts are safely separated from the supply voltages of the unit, from the sensor and contacts of the second relay, if there is any, up to a rated voltage of 250 V AC. They conform to the overvoltage category 2 and soiling degree 2.NOTE: If the relay is used to switch very low currents (e.g. plc inputs), considerable contact resistance can arise. The life of the relay contacts is considerably reduced by excess current or by the switching of unprotected inductive loads.Transistor output(A 300 with AC/DC switched-mode power supply)PNP, 24 V DC, ±20%, 700 mA, external supply at terminal 9. The voltage of the short-circuit protected transistor output is switched to terminal 10 depending on the selected function. It is not allowed to apply external vol-tage to terminals 10 and 11. |
