CLASSIC 800 Product Manual
LED Fault Indicator
The
CLASSIC 800
is designed so that any error condition will be immediately detected and displayed as a
FAULT
condition on the Display Panel.
•
The diagnostic circuit continuously monitors the operation of the heater, sensor elements,
connecting pathways and all the aspects of the Electronics Module.
•
To prev
ent any possibility of an intermittent FAULT the FAULT Code remains until the problem is
corrected.
•
When in FAULT MODE both relays will de-energize and remain de-energized.
•
The
4-20 mA
output can be programmed to rev
ert to a v
alue of either
3.0 mA
or
21
mA
to indicate
FAULT mode. For more information see
Section 2 “Installation Guidelines, View or Adjust the 4-
20 mA Fault Mode Configuration”
.
•
When connected to a PC v
ia Modbus, all FAULT Codes are automatically recorded in the EVENT
LOG in the Kayden RCM Software.
In the ev
ent a FAULT occurs, the Display Panel will display a FAULT LED. If the unit enters FAULT MODE
one of the following will be displayed:
Note:
*In FAULT Mode the CLASSIC 800 display cycles between:

Self-Test Error
Communication error between
the Electronics Module and the
sensor.
This condition may be caused
by an error in the Electronics
Module, internal connections
or the sensor itself.
Integral Unit:
Disconnect the Electronics Module and test
the sensor wiring (see Figure 1 1 ).
If the wiring resistance v
alues are
correct, the FAULT is in the
Electronics Module. The Electronics
Module must be returned to the
factory for repair.
If the wiring resistance v
alues are
incorrect the entire
switch/transmitter must be returned
for repair.
Remote Unit:
Repeat the tests as stated abov
e at the
electronics enclosure and the sensor enclosure.

Probe Error
When all 8 of the 40 - 75%
LEDs are

,
the sensor is not connected or
not making proper contact.
Ensure that the sensor connecting cable is
connected to the plug on the bottom of the
Electronics Module.
