9. Troubleshooting

Symptom

Probable Cause

Correction Steps

Power applied, display 

does not light, and con-

troller does not function 

1.  No power applied

2.  External fuse open 

1.  Check power wiring and fusing

2.  Power down and repower up 

Display alternates 

between 

HI and SENS, 

2110 disables control 

output 

1.  Open sensor

2.  Out of calibration 

1.  Check sensor wiring 

2.  Check selection switches 

3.  To verify that controller is at fault, re-

move the thermocouple and place a 

jumper across the sensor terminals 

of the 2110. If the display reads ap-

proximately ambient, then the sensor is 

open. Replace the thermocouple. 

4.  See Section 7–Calibration 

Process does not heat 

up 

1.  No power being applied to the load 

2.  Load fuse open 

1.  Verify Load LED is ON

2.  Verify the heater or fuse is not open 

3.  Verify output limit is set to 100% 

4.  Verify set point is greater than process 

temperature 

5.  Verify output wiring 

Erratic operation 

1.  Intermittent sensor connections 

2.  Controller failure (internal electronics) 

3.  External electrical noise

1.  Check sensor wiring or substitute sen-

sor simulator

2.  Power down and repower up

3.  Contact Chromalox

Process not in control

1.  Incorrect settings
2.  Thermocouple Wiring

1. Check Proportional Band setting and 

Automatic Reset setting

2. Check thermocouple polarity

Instrument continually 

goes through power-up 

reset

1.  Severe electrical noise

1. Separate sensor wiring from other wir-

ing

2. Apply power line filter
3. Contact Chromalox

The following Troubleshooting Guide offers simple so-

lutions to common problems and explains the 2110’s 

Error Messages. Review this section for a possible so-

lution to your problem before contacting Chromalox.

Note: For each symptom, perform correction steps in 

the order listed.
