CAUSE
SOLUTION
The Stage's fuse is
open.
Replace the fuse.
The display board
interconnect cable is
not plugged into the
power supply board
properly.
Make sure the cable is firmly
plugged in with the tabs in place.
The wiring is incor-
rect.
Correct the wiring. In particular,
make sure two different lines
are connected to each motor:
line L1 modulated by the
controller should be combined
with another line (N for 115V or L2
for 230V) to activate the motor or
heating unit. Also, make sure the
Stage COMMON is supplied by
line L1.
Verify if the motor or heating unit
is defective by connecting it to
an alternate power supply.
Replace the motor or heating
unit If it still is not operating.
The fan motor or
heating unit is
defective.
The controller is
defective.
Listen to see if there is a clicking
sound when the Stage's pilot
light turns on. If there is no
clicking sound, contact your
distributor to repair the control-
ler.
PROBLEME
One of the
other stages
is not operat-
ing.

Flashing Values:
The dis-
play will flash in certain cases
and not in others. The flash-
ing indicates that the value
shown can be adjusted. A
value that is not flashing can-
not be adjusted.

SING THE DISPLAY
Relative and Absolute Values:
Some parameter adjustments are displayed
both as a relative value and an absolute temperature. This applies to all heating
and cooling differentials, the mist differential and the heater offset. The
parameter is first displayed as a relative value. The corresponding absolute
temperature is displayed after six seconds if no action is taken by the user.
The absolute value is the temperature at which the stage turns on (except in
the case of the heater and mist offsets where the value displayed is the
temperature at which the stage turns off). If the user turns the adjustment
knob, the relative value reappears. For example, when the user turns the
selection knob to a differential position, i.e. STAGE 2/3, the sequence is as
follows:
(i) The current differential for stage 2 flashes on the display, alternating with
"
St 2
".
78.0
(ii) If, after about 6 seconds, no action is taken by the user, the absolute
temperature value is displayed, alternating with "
St 2
". In this case, the
absolute value is: Set Point + Ban Differential 2.
2.0
St 2
