Troubleshooting - Wolf CE152TF/S Technical & Service Manual

Troubleshooting

TROUBLESHOOTING
This section of the manual contains troubleshooting information to assist the Certified Service Technician in trou-
bleshooting a Wolf Integrated Module.
ELECTRONICS - CE152TF/S, CI152TF/S, and TM15TF/S
The control board and power board on the CE152TF/S, and the control board and generator assemblies on the
CI152TF/S and the TM15TF/S share the software for controlling the module. If a logic or programing issue is sus-
pected then the control board should be replaced first as it is the less expensive part.
Error E6 occurs whenever the module is connected to 120 VAC. If the module is to be used in Showroom mode,
then after the error occurs proceed with the steps to place the module in Showroom mode.
ELECTRONICS - SM15TF/S, FM15TF/S, and GM15TF/S
The module power board takes input from the user interface to set a temperature on the heating element(s) on the
module. The SM15TF/S and FM15TF/S use two Resistance Temperature Detectors (RTD) to maintain the desired
temperature on the module, and for input into the safety systems.
Where there is a difference in the performance of the electronics, it is noted.
Diagnostic Mode - All Models
Used to test the unit systems, view stored error codes, view real-time readings from system sensors, and to
enter/exit Showroom mode.
Entering Diagnostic Mode - CE152TF/S, CI152TF/S and TM15TF/S
1 Enter Lock Mode.
2 Touch and hold the "+" pad and "-" pad for 5 seconds.
3 After 5 seconds enters LED test, alerting the user to remove their fingers.
• If another key pad sensor detects a signal, Diagnostic Mode does not engage.
• If either the "+" or "-" pad is not released after 7 seconds, Diagnostic Mode does not engage.
• Power to all element assemblies is disabled.
• After 60 seconds if no input is detected the control returns to Lock Mode.
• ALL OFF pad exits Diagnostic Mode and the control returns to Lock Mode.
• There are no audible signals.
4 To step through the various tests touch the "+" and "-" pads.
• CE152TF/S and CI152TF/S: rear "..." display advances one LED for each test to identify which test is
being performed.
• TM15TF/S: front "..." display advances one LED for each test to identify which test is being performed.
Entering Diagnostic Mode - SM15TF/S, FM15TF/S and GM15TF/S
1 Enter Lock Mode.
2 Touch and hold the ALL OFF pad for 5 seconds.
3 After 5 seconds enters LED test, alerting the user to remove their fingers.
• If another key pad sensor detects a signal, Diagnostic Mode does not engage.
• If the ALL OFF pad is not released after 7 seconds, Diagnostic Mode does not engage.
• Power to all element assemblies is disabled.
• After 60 seconds if no input is detected the control returns to Lock Mode.
• ALL OFF pad exits Diagnostic Mode and the control returns to Lock Mode.
• There are no audible signals.
4 To step through the various tests touch the "+" and "-" pads.
• The "..." display advances one LED for each test to identify which test is being performed.
