Input: External Emergency Stop Connection
In addition to the Stop button on the PLC cabinet, the contacts OP1 and OP2 on Bank X5 are configured for an External
Emergency Stop function. It is a simple two- wire circuit, like a switch. When the circuit is closed (low resistance/continuity)
the system operates normally. When the circuit is open (high resistance/no continuity) the system will perform an Emergency
Stop.
There is normally a jumper/bridge wire between OP1 and OP2
so the system will operate normally without an External
Emergency Stop device. Remove the jumper/bridge wire when using these connections.

Output: External Alarm Indicator Connection
The Dositec’s main panel has a built-in alarm buzzer that is quite loud with a piercing sound, but it also has two contacts on
Bank X5, at A13 and M, that are designed to energize an additional, external alarm indicator.
The contacts are configured to supply
24 Volts DC, at up to 2 amps
, to energize an external alarm indicator, like a strobe,
buzzer or bell.
1) Positive Connection to A13
2) Negative Connection to M
