Configuration
The multi-position, rotary switches on the front face of a GSR safety relay
determine its functionality. The configuration method of a GSR safety relay
must provide means to help protect against manipulation and maintain
integrity of the configuration.
The rotary switches accommodate a small screwdriver to turn the switch to the
desired switch position. The configuration procedure implies a willing action
by the person who configures the safety function to prove that the person is
conscious and able to perform this task. Therefore, GSR safety relays require a
procedure of turning a switch to position “0” to start the configuration mode
and then turn to the position desired.
The status indicators on the front panel provide continuous feedback by
flashing the switch positions. Power cycling the device in a timely manner
completes the configuration mode and the device enters operation.
We recommend that the configuration is completed within 5 minutes. The
actual technical limitation of the internal EEPROM is around 8 hours. The
internal micro-controllers monitor and verify the switch positions during
configuration to achieve the required diagnostics coverage for the PLe safety
rating. The EEPROM read/write cycles are limited and can cause a permanent
fault of the GSR safety relay after several hours.
Switch Adjustment These safety relays have multi-position switches on their front face. Use a
small screwdriver to set the switches to the desired setting.

IMPORTANT To keep your GSR safety relay from permanently faulting, complete the
configuration process by power cycling the relay within 5 minutes after
configuring rotary switches.
Make note of the mechanical stop location.
IMPORTANT Adjust the switches gently and do not turn past the mechanical stops.
