8  TROUBLESHOOTING

 

 

 

Danger!

 

If the heater is energized while the cabinet door is open, an arc flash hazard may exist. 
Only trained personnel should attempt to energize the heater with the cabinet door 
open. 

 

Display is Not Illuminated

 

Cause: 

Solution: 

EMO button engaged 

Twist EMO in direction of arrows (see Section 2.3). 

No power at main circuit breaker 

Review wiring procedure (see Section 3, Installation). 

Control breaker is tripped 

Reset breaker 

Main breaker is OFF 

Main breaker to ON. 

Alarm Sounds

 

Cause: 

Solution: 

DI supply pressure 

Check water supply pressure at source. Verify supply is at least 
15 psig. 

Liquid level 

Check water supply at source. 
Check over-pressure relief diaphragm. 
Verify flow is on. 
Check plumbing for trapped air bubbles, see Section 4.1.e 

Leak sensor 

Check manifold and heater modules for leak.  Visually inspect 
leak tray. 

Thermocouple damaged 

If fault repeats, check thermocouple leads to OTC for continuity. 
Check T/C plugs in top heater modules. 

Plugged orifice in heater 

Check fluid lines in and out of manifold for flow. 

Over-temperature alarm 

Check if heater element has failed and replace module (see 
section 7.1). 
If fault reports, check T/C leads to OTC for continuity. 
Verify fan operation. 

Check for shorted SSRs (shut down per 7.1 before 
checking SSRs) 

Low/Stop Flow 

Check box on configuration page is checked, see section 2.4.f. 
Flow switch is set too low see section 2.4.f
