6.1  Maintenance & Troubleshooting 

 

Maintenance 

No preventive maintenance is required to ensure that  the SENTRY TIM-100/120 is in proper 
working order. 

 

Troubleshooting 

The following troubleshooting table will assist the user in identifying and correcting some of the 
most common problems.  Refer to the controller’s installation and operation manual for a 
complete guide. 

 

Problem 

Possible Cause 

Corrective Action 

(Tool Interfaced)

 Analog 

ground and power ground 
not connected or common 

Connect both analog ground and power 
ground.  Verify that they are common on the 
tool. 

Set point read-
back is always 
zero 

TIM-100/120 parameters 
incorrectly configured 

Ensure proper parameters are selected for 
the controller installed. 

TIM-100/120 parameter 
“STPT MODE” improperly 
set for installation 

Set TIM-100/120 parameter to “Analog” for 
analog communication or “Single” for stand-
alone or serial communication. 

(Analog Interface)

 

Analog interface 
improperly installed 

Properly install analog interface cable.  

(Serial Interface)

 

Serial cable improperly 
installed or address not 
set 

Properly install communication cable.  Adjust 
TIM-100/120 hex code to match tool settings. 

All set points not 
being achieved or 
cannot change 
set point 

TIM-100/120 parameters 
incorrectly configured 

Ensure proper parameters are selected for 
the model installed. 

Power not supplied 

Connect power. 

Both positive and 
negative voltage lines not 
supplied 

The negative voltage (-15 to -24 V @ 50 mA) 
powers the display.  Supply voltage 
according to the appropriate cable drawing in 
the Drawings section at the end of the 
manual set. 

Contrast not adjusted 
 

Adjust contrast using contrast knob. 

TIM-100/120 
display not on 

Blown Fuse 
 

Disconnect power and remove front panel.  
Replace fuse if necessary.
