the controller.
9)
WRONG
RAM
MEM
Cause:
The algorithm implemented to check the main RAM registers finds a wrong
contents: the register is “dirty”. This alarm inhibit the machine operations.
Troubleshooting:
Try to switch the key off and then on, if the alarm is still present replace the
logic board.
10) PUMP INC. START
Cause:
This is a warning for an incorrect starting sequence.
Troubleshooting:
The possible reasons for this alarm is (use the readings in the TESTER to
facilitate the troubleshooting) pump demand active at key on or a pump
demand is present without the seat input active.
Check the wirings. Check the micro-switches. It could be also an error
sequence made by the operator. A failure in the logic is possible too; so
when all of the above conditions were checked and nothing was found,
replace the controller.
11) ENCODER LOCKED #1
Cause:
The encode1 is stuck or the encoder signals are not correctly received by the
controller.
Troubleshooting:
Please check if the ENCODER1 on the tester menu is different than zero
during a lifting request.
Check the wirings and check that the sensor works correctly. A failure in the
logic is possible too; so when all of the above conditions were checked and
nothing was found, replace the controller.
12) ENCODER LOCKED #2
Cause:
The encode1 is stuck or the encoder signals are not correctly received by the
controller.
Troubleshooting:
Please check if the ENCODER 2 on the tester menu is different than zero
during a lifting request.
Check the wirings and check that the sensor works correctly. A failure in the
logic is possible too; so when all of the above conditions were checked and
nothing was found, replace the controller.
13) OUT PORT PULL-UP
Cause:
This is an alarm related to the hardware configuration.
Troubleshooting:
The problem is on the logic board, which must be replaced.
14) ANALOG INPUT
Cause:
There is a problem in the analog-to-digital module of the microcontroller. All
functions are stopped.
Troubleshooting: this a failure internal to the microcontroller, replace the
