Operation manual
•
Do not short-circuit the output line to the +24V line of the G9SR-BC□-□ because it
will set the output to (always) ON.
•
Do not connect the 0V of the power supply to Protective Earth (PE).
•
Ensure the configuration of the system complies with the required performance level
(PLr) of the safety control system that is defined during the risk assessment for the
machine according EN ISO 12100-1.
•
Do not connect any of the input lines to a DC power supply of more than 24V
DC+20%. Do not connect the input lines to an AC source. An AC power supply
(>30 VAC) may damage the unit.
•
Ensure that the AD201-□ and EX031-□ units are connected to the same power
supply.
•
Do not use the auxiliary output for safety applications.
● Power Supply Selection
Use a DC power supply satisfying the following requirements.
•
The secondary circuit of the DC power supply must be isolated from the primary
circuit by double insulation or reinforced insulation.
•
The output characteristic requirements defined in UL 508 for class 2 circuits or
control voltage current circuits are satisfied.
•
The output hold time must be 20ms or longer.
•
The DC power supply must be an SELV power supply that satisfies the requirements
of IEC/EN 60950-1 and EN 50178.
•
The power supply must be limited to a maximum current of 8A.
● Periodic Inspections and Maintenance
•
Disconnect the G9SR Safety Relay from the power supply before replacing the
Relay. Devices connected to the G9SR Safety Relay may operate unexpectedly.
•
Do not disassemble, repair, or modify the G9SR Safety Relay. Doing so may lead to
loss of safety functions.
● Disposal
Be cautious not to injure yourself when dismantling the G9SR Safety Relay.
This product has been designed to minimize environmental impact. For this reason
