E-61

real time clock error

Contact factory.

 

configuration connector

Refer to wiring diagram for the particular model and ensure dip switches on

E-70

the control match the settings called out on the WD. If the dip switch settings

error (dIp switch)

 

are correct according to the print replace the control.

 

 

E-78

Voltage low

Voltage below 90 VAC on a 125 VAC unit, or below 190 VAC on a

 

 

208-240 VAC unit. Correct voltage.

E-79

Voltage high

Voltage over 135 VAC on a 125 VAC unit, or over 250 VAC on a

 

 

208-240 VAC unit. Correct voltage.

E-80

EEprOM Error

Ensure that all temperatures and times are properly set.

 

 

Contact factory if problem persists.

E-81

EEprOM Error

Contact factory.

E-82

EEprOM Error

Contact factory.

E-83

EEprOM Error

Contact factory.

E-85

EEprOM Error

All timers, if previously on, are now off. Possible bad EEPROM.

E-86

EEprOM Error

Stored HACCP memory corrupted. HACCP Address reset to 1. Possible bad

 

 

EEPROM. Contact factory if problem persists.

E-87

EEprOM Error

All timer set-points are reset to 1 minute. Timers, if previously on, are now

 

 

off. Possible bad EEPROM.

E-90

Button stuck

A button has been held down for >60 seconds. Adjust control. Error will

 

 

reset when the problem has been resolved.

E-dS

datakey error

Datakey digital signature incompatible. Cycle power, and install compatible

 

 

Datakey if error persists.

E-dT

datakey error

Datakey incompatible with control. Install compatible Datakey.

E-du

datakey unplugged

Install Datakey and cycle power to control to clear error.

Note: If in doubt, always cycle the power to the control and contact factory if the problem persists.

To test probe and air sensor:

Test probe and air sensor by placing sensor in ice water bath and using an ohmmeter set on the ohm scale. The reading should be 100 ohms resistance. If it is more than 2 ohms higher or lower, sensor needs to be replaced.
