HR9Z-B2190 8/2020
Wire the terminals of the safety-related inputs according to the wiring diagram for the application
function ( see page 56 ) to be implemented.
Safety-Related Outputs
The wiring of the safety-related outputs depends on the safety-related function to be implemented.
Install fuses with the rating specified in the chapter Electrical Characteristics
( see page 28 ).
Start Input
The start input consists of one control output DC+ (terminal Y1) and one input channel CH+
(terminal Y2).
The control output provides a nominal voltage of 24 VDC to the connected sensor/device. It is also
used for dynamization ( see page 42 ).
The wiring of the start input depends on the start function
( see page 63 ) to be implemented.
For automatic start, bridge terminals Y1 and Y2 or connect terminal Y2 to an external 24 VDC
power supply.
For manual start or monitored start and if the control output Y1 (DC+) is to be used:

Connect terminals Y1 and Y2 to the device providing the start signal, such as a push-button.
For manual start or monitored start and if the device providing the start signal is supplied externally:

Connect terminal Y2 to the device providing the start signal, such as a push-button or a logic
controller. Leave terminal Y1 unconnected.
WARNING
INCORRECT USE/WIRING OF SAFETY-RELATED OUTPUT

Verify that the changeover output is not used for safety-related purposes if only terminals 11
and 12 are connected.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING
UNINTENDED EQUIPMENT OPERATION

Do not use the Start function for safety-related purposes.

Use Monitored Start or Startup Test if unintended restart is a hazard according to your risk
assessment.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
