MODEL 5318B
Level Tek II, Capacitance Level Switch
SECTION V – TROUBLE
SHOOTING

5.1 STATUS LED

The Model 5318B is constantly checking its
status. The STATUS LED (DS203) will flash at
the rate of approximately once every two (2)
seconds to indicate that the electronics are
functioning correctly.
If the LED is not flashing the instrument may be
reset by removing power from the instrument for
a minimum of 10 seconds. If the LED is still not
flashing contact your nearest ROBERTSHAW
Industrial Products Representative for
replacement parts.

5.2 ERROR CODES

There are also a number of Error Codes that are
displayed to indicate various detected out of
range values.
5.2.1.
ERROR 01 – Reserved
This error code is reserved for future
use.
5.2.2.
ERROR 02 – Measurement Too
High
This error code alerts that the current
raw measurement value is too high (the
sensed capacitance is too low).
The most common cause of this error is
an open circuit to the probe and the
most common cause is a failure to
install the probe pin.
If the probe pin is installed contact your
nearest ROBERTSHAW Industrial
Products Representative for assistance.
5.2.3.
ERROR 03 – Measurement Too
Low
This error code alerts that the current
raw measurement is too low (the sensed
capacitance is too high).
The most common cause of this error is
improper control range selection. If this
error occurs refer to paragraph 4.4.1.
Another cause of this error is a shorted
probe. To check for a shorted probe
follow the following procedure:
•
•
•
•
If changing the control range or a
shorted probe is detected, contact your
nearest ROBERTSHAW Industrial
Products Representative for assistance.
5.2.4.
ERROR 04 – Low Setpoint Too
Close or Reversed.
This error code alerts that the low
setpoint level being calibrated is higher
than the high setpoint level.
5.2.5.
ERROR 05 – High Setpoint Too
Close or Reversed
This error code alerts that the high
setpoint level being calibrated is lower
than the low setpoint level.

INSTRUCTION MANUAL
909GF295
Remove power from the
instrument.
Remove the cover from the
instrument.
Remove the electronics
assembly from the base of the
housing by loosening the three
(3) captive screws and pulling it
straight up, out of the base.
With a Multi-Meter measure the
resistance between the probe
pin and the base. This value
should be greater than 3
Megohms.
