*1 Do not connect anything to these pins.
*2 A critical error occurs if the input values from the Safety Door 1 and Safety Door 2 are
different for two or more seconds. They must be connected to the same switch with two
sets of contacts.
*3 A critical error occurs if the input values from the Emergency Stop switch contact 1 and
Emergency Stop switch contact 2 are different for two or more seconds. They must be
connected the same switch with two sets of contacts.
*4 Do not apply reverse voltage to the Emergency Stop circuit.

The total electrical resistance of the Emergency Stop switches and their circuit should
be 1 Ω or less.
CAUTION
The 24 V output is for emergency stop. Do not use it for other purposes.
Doing so may result in system malfunction.
Do not apply reverse voltage to the Emergency Stop circuit.
Doing so may result in system malfunction.
