To perform one of the memory test functions, enter the function number using the nu-
meric keys and press SEL.
Description This menu selection provides several functions listed below.
Function 7000
Clears all pulses and configuration settings from the controller’s EEPROM. After
clearing the pulses, the controller will reload the factory default settings.
When the function is complete, the address of the last memory location cleared is dis-
played. Press ESC to continue.
The PLS will then reset and the PS-6400 keypad will show "EEPROM reset to factory
defaults".
Function 7001
Clears all configuration settings from the controller’s EEPROM. These include all
programming other than pulses. When finished, the controller will reload the factory
default settings.
When the function is complete, the address of the last memory location cleared is dis-
played. Press ESC to continue.
The PLS will then reset and the PS-6400 keypad will show "EEPROM reset to factory
defaults".
Function 7002
Clears all pulses from the controller’s EEPROM.
When the function is complete, the address of the last memory location cleared is dis-
played. Press ESC to continue.
Function 7998
Watchdog Timer Test. The “Watchdog Timer” monitors the operation of the controller’s
microprocessor and shuts the controller down if any internal malfunction is detected. If
the Watchdog Timer fails, the controller may continue to operate. However, any subse-
quent malfunctions or noise-induced irregularities may go undetected, and the control-
ler may begin to operate erratically.
To test the Watchdog Timer, run Function 7998. If the controller’s Watchdog Timer is
working properly, the controller will reset and the display will show "STATUS WATCH-
DOG TIMER TIMEOUT". If Function 7998 does not reset the controller, the Watchdog
Timer has failed. Replace the controller immediately and return the faulty unit to the
factory.
Failure of controller to pass the watchdog timer test can cause erratic operation,
resulting in injury and damage to equipment.
