RESTART INTERLOCK CONNECTIONS
The hardware channels of the restart interlock circuit are controlled using the RESTART
INTERLOCK connector.

RESTART INTERLOCK CONNECTOR
Mating connector: 10 contacts, series MC 1,5/10-STF-3,81 by Phoenix
Pin Name
Function
1
- “Channel 1”
0V input to coil of RL1 Safety Relay Channel 1.
2
+ “Channel 1”
Input to coil of RL1 Safety Relay Channel 1. With the input active this input must
be high (+24Vdc). When the input is inactive this input must change to low (0V).
3
- “Channel 2”
0V input to coil of RL2 Safety Relay Channel 2.
4
+ “Channel 2”
Input to coil of RL2 Safety Relay Channel 2. With the input active this input must
be high (+24Vdc). When the input is inactive this input must change to low (0V).
5
6
“Channel 1
verification”
NC contact
NC contact of RL1 Safety Relay of Channel 1. Feedback of RIC. When closed
(high), the Restart Interlock function is active. The external verification system
must monitor this output signal for consistency with its input signal
7
8
“Channel 2
verification”
NC contact
NC contact of RL2 Safety Relay of Channel 2. Feedback of RIC. When closed
(high), the Restart Interlock function is active. The external verification system
must monitor this output signal for consistency with its input signal
9
NO contact
Series of NO contacts of RL1 and RL2 relays.
