7.5 RELAY

SUPERVISION

7.5.1 GENERAL

The Ancillary relays (Anc1 and Anc2) and Bells relay on the MAF/PSU, and the Module

relays all have the option of supervision (i.e. checking the wiring from a relay to its load to

see that it is not "short" or "open" circuited).

In F3200, the supervision also includes a "confirmation" function i.e. it expects to "see" a

different state after a relay has been activated. If an incorrect state is "seen" by the

supervision, before or after relay activation, then it generates a "fault" condition for that relay.

Supervision in the activated state can be disabled for “load” mode if it is not required, for

example when the relay switches the load to 0V.

For each relay the supervision can be disabled if not required, mapped to the MAF, and

made latching or non-latching. Anc 1 + 2 relays can be programmed for two different modes

of supervision - door holder or load mode. All relays can also be individually made non-

isolatable (stops the Operator isolating them) and non-testable.

The Relay (Supervision) menu (Option 5 on the System Configuration menu) has two

options as follows: 1 Bells/Ancillary Relays; 2 Module Relays. The options for selecting

relays as Isolatable, Testable and Supervise Activated state are available in V2.09 or later

software.

7.5.2

BELLS & ANCILLARY RELAY SUPERVISION

This is option 1 in the Relay Supervision menu.

Refer to Section 3.4.2 for the electrical characteristics of the Bells and Anc1, Anc2 relay

supervision.

Ancillary Relay Supervision

The options which may be entered for Anc1, 2 and Anc3 are:

Supervision enabled (E) or disabled (D).

Supervision latching (L) or non-latching (N) (i.e. the fault condition).

Fault and isolate mapped (M) or not mapped (N) to the MAF.

Supervision is load (L) or door holder (D) mode (not for ANC3).

Isolatable (yes/no)

Testable (yes/no)

Supervise Activated State (yes/no)

The default setup (by EEPROM initialise) is.

ANC 1: supervision disabled, non-latching, mapped to MAF, Door holder, isolatable,

testable, activated state supervised.

ANC 2: supervision disabled, non-latching, mapped to MAF, Load mode, isolatable,

testable, activated state supervised.

ANC 3: supervision disabled, non-latching, mapped to MAF, isolatable, testable, activated

state supervised.
