1. Short Description

The safety relay PSR-ESD-T can be used in emergency off devices and in safety circuits in acc. with
DIN EN 60204-1/VDE 0113 Part 1. Depending on the external wiring, safety category 4 is the maximum
that can be attained for the undelayed contacts and safety category 3 for the dropout-delay contacts, in
acc.with EN 954-1.
Control is carried out via one or two channels with manual or automatic activation. A connected reset
button is monitored.
The relay has three enabling current paths and one signaling current path that drop out undelayed in
compliance with DIN EN 60204-1/VDE 0113 Part 1.
Two other enabling current paths drop out delayed in compliance with Stop category 1 in acc. with
DIN EN 60204-1/VDE 0113 Part 1.

4. Assembly and Startup

To ensure reliable operation, the EMERGENCY STOP safety relay must be mounted in an IP54 housing
that is protected against dust and humidity.
Carry out the wiring in accordance with its intended purpose. Use the sample applications as a reference
(page 16).
In order to comply with the UL, use copper cables that are designed for operating temperatures of > 75°C.
For reliable and shock-proof contacts strip the connecting ends:

In general, the safety relay is to be wired according to the following instructions:
4.1. Wiring - Activation and Feedback Circuit
Automatic activation:
Connect a bridge between S33 and S35 and
a bridge between Y1 and Y2.
Automatic activation with
monitored contact expansion:
Connect a bridge between terminal blocks S33 and S35
and connect the N/C contacts of the expansion contactor
to terminal blocks Y1 and Y2.
Monitored reset:
Connect a reset button between terminal blocks S33 and
S34 and connect a bridge between terminal blocks Y1
and Y2.
Monitored reset with
monitored contact expansion:
Connect a reset button to terminal blocks S33 and S34
and the N/C contacts of the expansion contactor to
terminal blocks Y1 and Y2.

2. Safety Notes:

• Observe the electrotechnical safety regulati-
ons and those of the trade association!
• Ignoring the safety regulations can lead to
death, serious injury or cause considerable
damage!
• The device may only be started up,
assembled, modified or retrofitted by an
authorized electrician
• Before starting work, disconnect the device
from the power supply!
• In emergency stop applications, a higher
level control unit must ensure that the
machine cannot start up again
automatically!

3. Function

The activation and input contacts S33, S34, S35, S10, S11, S12, S21, S22 must be wired in accordance
with the intended purpose (see "Assembly and Startup" and "Sample Applications").
Once the nominla input voltage has been applied to terminal blocks A1 / A2 or GND, the "Power" LED
lights up.
Depending on the external wiring, the PSR-ESD-T is started either automatically or manually when the
safety door is closed or the Emergency Stop switch is deactivated (see "4.1. Wiring - Activation and
Feedback Circuit" on page 14). The contacts 13/14, 23/24, 33/34, 57/58, 67/68 close and the alarm con-
tact 41/42 opens. LEDs K1, K2, K3(t) and K4(t) are illuminated.
If the input circuit is opened, relays K1 and K2 drop out undelayed and the LEDs extinguish. Relays K3t
Fig. 1
and K4t drop off delayed.
The module can be reactivated when the input circuits are closed and the module is started either
manually or automatically.

Two-channels with cross-circuit protection:
Connect the N/C contacts of the tripping element to
S11/S12 and S21/S22 and bridge S10/S11.
One-channel:
Connect the N/C contact of the tripping element to
S11/S12. Bridge S21/S22 and S10/S12.

• During operation, parts of the electric
switchgear carry high voltages!
• Danger! During operation, the protective
covers must not be removed from the
electric switchgear!
• The device must always be replaced after the
first malfunction!
• Repairs to the device, especially
those involving opening the housing, may
only be carried out by the manufacturer or by
a person authorized by the manufacturer.
Otherwise the manufacturer's guarantee
automatically expires!
• Keep the operating instructions!
