8.10 TROUBLESHOOTING

Faults which may occur during WHM operation include the items listed in Table 8-3.

Table 8-3. WHM Troubleshooting

FAULT INDICATION

PROBABLE CAUSE

CORRECTIVE ACTION

OUTLET
TEMPERATURE
display is flashing on 2
C- More Control Panels

1.

Two C-Mores have their
WHM Mode menu option
set to WHM Master

1.

Check the WHM Mode entries in
the units which have their displays
flashing. Change one of the WHM
Mode settings to WHM Slave.

REMOTE LED on one
or more WHM units is
Off.

1.

Improperly connected or
faulty RS485 Modbus
wiring.

2.

Improper Comm address.

3.

Unit Comm address is
not unique.

1.

Check the polarity of the RS485
Comm connections on the I/O
board of the affected unit. Also,
ensure that all Modbus wiring
connections to the unit are secure.

2.

Verify that the address of the
affected unit is within the allowable
range (1 thru 8).

3.

Check to ensure that none of the
units have the same Comm
address.

Actuator-controlled
sequencing valve does
not open

1.

Control cable not
connected to valve
actuator.

2.

24 VAC power not being
supplied to valve
actuator.

3.

Defective valve actuator.

1.

Ensure that the control cable from
the unit’s I/O Box is connected to
the valve actuator.

2.

Remove the enclosure cover from
the valve actuator and verify that 24
VAC is present at Terminal 2 of the
actuator.

3.

Replace valve actuator. Following
replacement, the actuator stroke
will have to be calibrated to ensure
it fully opening and closing.

8.11 SEQUENCING VALVE DESCRIPTION & OPERATION

Brief descriptions of Actuator-Controlled Sequencing Valve, part no. 92093 and its operating
characteristics are provided in sections 9.11.1 and 9.11.2, respectively. The installation of the
valve itself is described in Chapter 2, section 2.5.1.

8.11.1 Sequencing Valve Description

The Actuator-Controlled Sequencing Valve shown in Figure 8-5 is comprised of the following
main components:

•

2” Brass Ball Valve

•

Actuator Linkage

•

Actuator Housing

•

Valve Shaft Handle
