Temperature Monitoring - Sensaphone 1104 User Manual

Temperature Monitoring:

Problem
1. Can't program temperature limits; or the
unit won't read the temperature sensor.
2. The temperature reading is -20° F
or -30° C.
3. Temperature reads 150° F
or 65° C.
4. Temperature reading is inaccurate.
Cause
The input isn't configured to read a tempera-
ture sensor.
The temperature sensor has been
disconnected or has broken wires.
Temperature sensor wires are touching or
have shorted.
a) Temperature sensing may be affected by
a source of ambient heat (ie., direct
sunlight, or heat duct proximity).
b) Temperature may require calibration.
c) The unit is using the wrong temperature
scale (Fahrenheit vs. Celsius).
Solution
Press SET and CONFIGURE to program the
input. (See Section 5.1.1 for more information
on configuring inputs.)
Examine the wires to temperature sensor and
connect or replace wiring.
Verify and correct wiring.
Try moving the unit to a different location.
After moving or placing the unit away from
ambient heat sources, the temperature may be
calibrated to offset inaccurate normal reading
by several degrees.
Refer to Chapter 5, Section 5.6.
Verify temperature scale.
Refer to Chapter 5, Section 5.5.
