79 79 INCORRECT START Control sequence not correct The possible reasons for this alarm are (use the readings on
the TESTER menu of the console to facilitate
troubleshooting):
A) A command already active at system’s start -up
B) A command active before the dead-man pedal contact is
closed;
C) Dead-man pedal contact already active (closed) at start-
up;
Check wiring. Check the joystick microswitches.
Check you meet the sequence for a command: press the
dead-man pedal first and then operate the joystick of the
required command.
If the problem persists after the above checks, the error may
be caused by a failure of the controller logic or CAN Tiller
board: in this case, replace the device.
79 242 PUMP INC START Pump start incorrect The reasons for this alarm may be:
A) Request to pump drive already active at start-up;
B) Request to pump drive active without closing the dead-
man contact.
Check the wiring and the correct operation of microswitches.
Check that the control procedure has the correct sequence:
press the dead-man first and then start the requested
command.
If the problem persists, a fault in the internal circuit may be
present.
In this case replace the controller.
80 80 FORW + BACK Simultaneous Forward-
Backward control
Check wiring of microswitch inputs of Forward and
Backward drive.
Use a TESTER to check the correct operation of
microswitches.
If there are no errors in wiring and microswitches work
correctly, the problem may arise from a logic fault: replace
the controller.
82 82 ENCODER ERROR Drive motor encoder error A) Check the electrical and mechanical functionality of the
encoder and wiring.
B) Check the mechanical installation of the encoder, if the
encoder is inserted correctly inside its own housing.
C) Also the electromagnetic noise on the sensor bearing
may be cause for alarm. In these cases, try replacing the
encoder.
D) If the problem is still present after replacing the encoder,
the error is in the controller, which must be replaced.
82 200 INPUT MISMATCH Input error not consistent The alarm is displayed when an input, made redundant on
multiple devices (Master and Slave controller, controller and
CAN Tiller board) to increase safety, has different values,
not consistent.
(e.g. the tilt sensor is read by both controllers. The alarm is
displayed if the value read by a controller differs from that
read by the other).
If possible connect the console and spot which input creates
the problem: check the wiring connection between the
sensor/limit switch and system devices (controllers, boards).
If there are no errors in the wiring, try disconnecting the
sensor/limit switch.
If the problem persists, one of the 2 devices monitoring the
sensor may have failed.
In this case, replace the device (controller or CAN Tiller
board).
82 201 INPUT MISM. SLV Redundant input error not
consistent
