angle/length #
5 volts reference voltage is not valid (if
< 4.5 volts or > 5.5 volts).
1- Angle/length circuit board
is defective.
B) Load interface circuit board errors:
The i3500 system can support up to 4 load circuit boards. Activation of every load
sensor is done in the calibration menu section “-ent/sor activate/deactivate”.

Off limits load #
Angle sensor value in bits is not valid
(if < 150 or > 3935).

Load card is defective.
Communication
load #
I3500 system does not receive data
from pressure sensor. If “time out”
delay is reached, then a
communication error is displayed.
1- Load card is defective,
2- Can Bus network cable is
broken.
C) Relay and digital input interface board errors:
The i3500 system can support up to 4 relay cards. Activation of every relay card is
done in the calibration menu section “-ent/sor activate/deactivate”.
Error message
Execution process
Cause of error
Communication
relay #
i3500 system does not receive data
from relay card. If “time out” delay is
reached, then a communication error
is displayed.
1- Relay card is defective,
2- Can Bus network cable is
broken.
Note: There is no automatic test for the relay contacts on the relay circuit board.
Therefore, if a relay becomes defective there may not be a warning. Periodically, the
operator should test the lockout system.
D) Generic interface board errors:
The i3500 system can support up to 4 generic cards: One for wind speed, one for
inclination level, one for absolute rotation and another one for analogical output.
Activation of every generic card is done in the calibration menu section “-ent/sor
activate/deactivate”.

An appropriate, analogical sensor is
not calibrated.

5 volts reference voltage is not valid (if
< 4.5 volts or > 5.5 volts).
1- Generic card is defective.
