1.6 Monitoring print The monitoring print is used for monitoring defined values of the valve and to provide the user with information on this. It can be equipped with up to four BCD switches and can be connected to the position signalization. The following switches can be used optionally:

1. Cycle time extension2. Cycle time monitoring3. Cycle counter4. Motor current monitoring

1.6.1 Cycle time extension Cycle time extension is used to prevent pressure surges in the system, by closing the valve more slowly.

1.6.2 Cycle time monitoring Cycle time monitoring is used for an early detection of problems at the valve or in the process, which are reflected in extended cycle times.

1.6.3 Cycle counter The cycle counter is used to inform the user, as soon as the set number of cycles is reached. The user can choose, whether the motor should stop afterwards or keep running.

1.6.4 Motor current monitoring If a valve becomes sluggish over time, due to crystallizing media or foreign substances, the motor current will increase. Motor current monitoring is used to immediately detect and localize malfunctions of that kind. It can also be defined, at which motor current it will be switched off. In combination with the position signalization, the valve position can be fed back via a 4-20 mA signal.

The product is not intended for any types of use other than those described here. Non-observance of the instructions contained in this manual will void the manufacturer's liability for the products mentioned above.

8.3 Assembly

If additional limit switches are used, the position signalization will always be installed above these limit switches.

Disconnect the actuator from the supply voltage. Remove the screws of the limit switches S1 and S2. Remove position indicator 1. Attach circular magnet 3, so the notches are on top. Put position indicator 1 in one of the end positions on the axis. Connect board 8 of the position signalization to the controller or monitoring print

by using system cable 2. Connect the supply voltage.

The board has been connected correctly when the LED 6 lights up green.

8.4 Performing a learning run

If the position signalization was mounted at the factory, a learning run with 360 ° has already been done. In this case, the jumper is placed on only one pin. If the position signalization is mounted by the customer, a 360 ° learning run has to be done. Therefore, the two pins need to be connected by the jumper.

In order for the position sensors to detect the 4 positions:Connect both PINs with jumper 7 and carry out one learning run with 360 °.

In order to determine, whether the learning run happens with 360 ° or between the end positions: Plug jumper 7 on the position signalization:

o Jumper connects both PINs: Learning run 360 °

o PINs not connected: Learning run between the end positions S1 and S2

For this, press button 5 (approx. 2 s).LED 6 will go out briefly.

As soon as the LED lights up again: Release the button.The actuator carries out a learning run, with LED 6 flashing at the same time.

While LED 6 is flashing, the actuator is in the learning run mode.

The learning run is finished correctly when the LED lights continuously.

Ensure that the LED lights up continuously.OPEN and CLOSED positions are adjusted.

Depending on the switching cams S1 and S2: Carry out further learning runsbetween the end positions.

Position signalization Accessories for electrical actuators

For new learning run 360 °: Disconnect the actuator from the valve, to avoid damage to the valve. Before doing the learning run, set the jumper so it connects the two pins. Perform the learning run. Put the jumper into the original position. Mount the actuator.

Fig. 11

If the position signalization is combined with the monitoring print, the output signal 4 – 20 mA can be processed on the terminals (18 and 19) 9 on the board of the monitoring print. (4 mA > CLOSED / 20 mA > OPEN).

If the position signalization is connected to the positioner, the positioner will process the signal.

10.4 Eliminating a malfunction message

Fig. 21

In case of a malfunction message, the red LED 8 on the base board will light up. If the monitoring print is installed, the respective LED 10 lights up red on the BCD switch, if its set value is exceeded. On all occurring malfunction messages, the relay of the ready-to-operate signal de-energises, i.e. there is no continuity on terminals 5, 6, since the contact is interrupted.

Check the cause of fault. If necessary, carry out relevant maintenance.
