Important remarks
Reaction times
The total reaction time is the sum of:
•
Reaction time of the motion monitor and
•
Fall time of the output relay (<20ms). and
•
Fall time of any external devices.
The reaction time of the motion monitor decreases as the speed to be monitored increases (linear). It measures at
5 Hz about 200 ms and at 1000 Hz about 1 ms.
Fault trip
will be stored in the unit and will be displayed via LED (see “Fault-Errors”). To reset the fault memory
terminal A1 must be disconnected.
Installation
The safety relay must be cabinet mounted (min. IP 54). There are 2 screws left and right at the housing for DIN-rail
attachment.
Operation
Please note for operation:
•
To prevent a welding together of the contacts, a fuse (6 A slow acting) must be present in the output circuit.
•
The total of the reaction times must not lead to a dangerous status.
•
Use copper wiring that will withstand 60/75°C.
Important details in the section “Technical Data” should be noted and adhered to.
•
Supply operating voltage to terminals A1 (+) and A2 (-).

Programming
Wiring of the automatic mode at monitoring modules with D- and F-inputs
The necessary D-inputs for the monitored speed have to connect directly to 24V DC.
The necessary F-inputs for the monitored speed have to connect to 24V DC via the switch of protection cover.
Wiring of the automatic mode at monitoring modules with only D-inputs
The necessary D-inputs for the monitored speed have to connect to 24V DC via the switch of protection cover.
Wiring of the tool setting and the semi automatic mode at all monitoring modules
Connect the SH-input for tool setting mode via safety switch to 24V DC.
Connect the R1-input for semi automatic mode via safety switch to 24V DC.
Measurement system
Connect an encoder for each monitoring system to the NC and DNDS via DNDA or use 2 PNP-proximity sensors
for each monitoring system connected to IN1 and IN2.
