5.4.2 Operation and wiring of safety relays K1-K2.
The safety stop chain is cut out by safety relays K1 and K2 (internal to receiver) which control the contacts
accessible by terminals 22-23 and 32-33.
The state of relays K1 and K2 depends : on the position of the trigger (table 1), possible faults detected, and
possible radio link losses.
Other external safety stop devices can be added including an emergency stop palmswitch and a gate control
device, wired to the inputs provided for this purpose on the receiver. The state of the inputs will act directly on
relays K1 and K2 through the receiver.
The state of safety relays K1 and K2 is available between terminals 13 and 14.
State of safety outputs as a function of enabling handle trigger position :
