Multi-Circuit Standard Ambient Temp Sensing Digital Controller
Changing Set-Point Values
To change the Heater-On and Low-temperature Cutout set-point values, follow the
steps below with the controller powered and the rocker switch set to AUTO:
1)
Press the SET button once to display the current Heater-On set-point value
(displays temperature in tenths of degrees). A red indicator light under “out1" will
appear.
2)
Press the UP or DOWN arrow button to adjust the value. Hold button to scroll.
3)
Press the SET button again to display the current Low-Temp Cutout set-point
value. A red indicator light under “out2" will appear.
4)
Press the UP or DOWN arrow button to adjust the value. Hold button to scroll.
5)
Press the SET button again to return to the normal operating mode (will display
the current sensed temperature with no decimal point.)
Low-Temp Cutout can effectively be avoided by setting its value below the lowest
expected ambient temperature (for example: -50.0.)
NOTE: Multi-Circuit controllers default start-up temperature is set to 36
E
and
should be adjusted to actual field needs.
Alarm Buzzer and Error Messages
If the alarm buzzer sounds, it can be silenced by simultaneously pressing the SET and
Down buttons. The alarm message will continue until condition is corrected.
Common Error Messages
1) “ErP” = Error of the probe not shown on display
2) “ooo” = Open sensor (one or both sensor leads are not connected).
3) “- - -” = Shorted Sensor (direct short between sensor leads).
