FAtL int Internal Run Error
There is a hardware problem with internal circuitry. All outputs will be disabled.
Solution: Call Electro Cam for return authorization and further information.
LinEFAiL Input Power Voltage Low
The input power to the controller dropped below normal operating voltage, causing the controller to stop
functioning. Check that input supply voltage to controller is within specified operating range (pg.A-18).
Solution: Control will come out of “LinEFAiL” condition when input voltage rises to normal range.
Pb Stuc Push Button Stuck
If one of the keyboard keys is on when the unit powers up, this message will be displayed. It can indicate
that a key is shorted and always on.
Solution: If “Pb Stuc” error message remains or occurs frequently on power up, call Electro Cam for
further information.
StoP Controller in Stop Mode
When Serial Communication Command 6 (COM_STOP) is sent to the control, it goes into an idle mode
and displays the message “StoP”. The Stop mode allows serial information to be written directly into the
control's EEPROM memory, thus allowing rapid loading of program information. The PLuSNET DLOAD
(down load) program first puts the control in the Stop mode before sending information. When the
loading process is complete it returns the control to the run mode. If the loading process is interrupted,
the control might accidentally be left in the Stop mode.
Solution: Power cycle the control to restore normal operation.

RS-485 can be used for “Multi-Drop” communication (more than one controller connected simultaneously).
RS-232 can be connected to only one control at a time.
For standard 485 communications, pin 4 must be connected to pin 6. If pins 4 and 6 are not connected,
controller will communicate with remote display, which will interfere with standard 485 communications.
Error Messages (Continued)
*Pins 1, 4, 6, 7, and 8 must not be connected!
Damage may result from using an off-the-shelf RS-232 communications cable.
