Setting up the Interlock Relay (Force On) Feature

Relays 1-4 can be set up as interlock relays. To set up the relays for the interlock feature:

1. Access the

Setup

–

Relay

–

Action

menu and set the action to off.

2. In the Advanced features –

User

menu program any of the digital inputs to

Force On

any of the

internal relays (1-4).

3. Connect a switch or dry contact between the +5V terminal and the corresponding digital input (dI-

1 to dI-4) terminal.

Interlock Relay Operation Example

Relays 1 & 2 are configured to energize (their front panel LEDs are off) when SW1 & SW2 switches

(above) are closed. If the contacts to these digital inputs are opened, the corresponding front panel LEDs

flash indicating this condition. The processes being controlled by the interlock relay will stop, and will re-

start only after the interlock relay is re-activated by the digital inputs (switches).

Note: If multiple digital inputs are assigned to the same relay, then the corresponding logic is (AND) – i.e.

both switches must be closed to trip the relay.
