CIRCUITS & ZONES (CONTINUED)

For

options A and C

in Fig 9.1.3, configure circuit Alarm Text as "manual" and voltage band

B1 as "Instant Alarm" (refer to table below).

Voltage Default Program Fan

Band State

State Control

B5 Fault Switch wiring open circuit

B4 Normal "Auto"

B3 Normal "Auto"

B2 Alarm "Off"

B1 Inst Alarm "On"

Configure the zone as non-latch, Status, non Anc1/Anc2/Bells.

In output logic, "off" is ZnD, "On" is ZnM, (for AZC number n).

For

Option B

in Fig 9.1.3, configuration is similar but in the output logic, "off" is ZnF and "on"

is ZnA.

For two AZC inputs:

┌──┐

┌───────┬─────────────────────────────┤ │+

OFF o │ │2K7 AZC 1

└┬┘ ┌──┐

AUTO o───o───┼─────────────────────────────┤ │-

FIG 9.1.4

FAN CONTROL WITH TWO AZCs & ROTARY (OR CENTRE-OFF) SWITCH

Program B1 for both AZCs as "Instant Alarm", Alarm Text as "Manual".

Zone 1 Alarm "Fan Control Off"

Zone 2 Alarm "Fan Control On"

Both Normal "Fan Control Auto"

Configure both zones as non-latch, Status, non Anc1/Anc2/Bells.

Fan Inputs

The exact requirement depends on the particular fan motor controller, and the contacts

available (e.g. "Run", "Fault"). Commonly "Run" is provided by an air flow switch (AFS), and

is required to connect to an AZC so that it can become part of a logic equation (as per

circuits 3 & 4 of standard module 1945-1-1/4 following).
