Safety Instructions
–
–
–
During operation, parts of electrical switching devices carry hazardous voltages.
Before working on the device, disconnect the power.
Please observe the safety regulations of electrical engineering and industrial safety and liability
associations.
Disregarding these safety regulations may result in death, serious personal injury or damage to
equipment.
Startup, assembly, modifications, and upgrades may only be carried out by a skilled electrical
engineer.
For emergency stop applications, the machine must be prevented from restarting automatically by
a higher-level control system.
Protective covers must not be removed when operating electrical switching devices.
In the event of an error, replace the device immediately.
Repairs, especially if the housing must be opened, may only be carried out by the manufacturer or
authorized persons. Otherwise the warranty is invalidated.
–
–
–
–
–
The device must be operated in a closed control cabinet (according to EN 61508-6:2001, Table 01).
When operating relay modules the operator must meet the requirements for noise emission for electrical and
electronic equipment (EN 61000-6-4) on the contact side and, if required, take appropriate measures.

PSR-...- 24DC/SSM/2X1
Function
If the 24 V DC operating voltage is applied at terminal
blocks A1 and A2, the electronics checks (in the stop state)
whether at least one of the proximity switches provides a
signal at input IN1 or IN2.
The FO diagnostic output indicates the ready state with
+24 V. The "Power" and "Mode" LEDs light up. If this is the
case (one or both proximity switches provide a signal), the
internal output relays switch to the operated condition. N/O
contacts 13-14 and 23-24 are closed, N/C contacts 31-32
and 41-42 are open, and the "Output" lights up. Alarm
output MO indicates +24 V.
The outputs remain active in their switch position as long as
no signal change is generated at inputs IN1 and IN2 by a
movement.
N/O contacts 13-14 and 23-24 open and N/C contacts
31-32 and 41-42 close if a signal change with a frequency
> 2.5 Hz is detected at inputs IN1 and IN2. Alarm output MO
is a high-resistance output.
If the input circuit frequency is less than 2 Hz (stop state
entered or movement not hazardous), relays K1 and K2
switch. N/O contacts 13-14 and 23-24 are closed and N/C
contacts 31-32 and 41-42 are open. Alarm output MO
indicates +24 V.
In the event of an error (sensor error), the "Mode" LED
flashes and FO is a high-resistance output.
For a connection example, please refer to page 6.
Assembly and Startup
Before working on the device, disconnect the power.
In order to comply with UL approval, use copper cables that are designed for operating temperatures > 75°C.
For reliable and safe-to-touch contacts, strip the cable ends as follows:
