2 Extending the Probes
Each probe can be extended up to 500 feet (150 meters). To extend a probe:
n
Use a shielded cable of outside diameter between 0.245 and 0.260 in
(6.22 and 6.60 mm) (the cable dimensions should not be under 18
AWG) to ensure the cable entry is liquid tight. Do not ground the
shielding.
n
It is preferable to solder the cable joint to ensure a proper contact
between the two cables.
CAUTION:
crossing over other cables, cross at 90°.
3 Defective Probes

room temperature shown on the display is then the average temperature
measured by the probes in working condition. The controller will operate
according to this temperature.
To identify the defective probe:
n
Set the selection knob to ROOM
TEMPERATURE . The room
temperature is displayed.
n
Press the push-button. If the
probe connected to input # 1 and
supplied with the controller is not
defective, the letters"PR1" are
displayed, alternating with the on/
off state of the probe and the tem-
perature measured by the probe.
If the probe is defective, the let-
ters "PR1" are displayed, alter-
nating with the state of the probe
