13.9.11 Magnetic pickup wire break
This alarm is for magnetic pickup wire break. If the engine is running but there is no
pulse for 2 seconds, then the controller monitors the cable. If there is no change during
the alarm delay time, then the controller activates the alarm.

13.9.12 Analogue input (AI) characteristics
This analogue input can be configured as either current (0 to 25 mA) or resistance (0 to 2500 ohm). Using a configured or selected
input curve, the controller converts the input to a corresponding value. You can also configure the input to activate functions and/or
alarms.

Maximum voltage
This input is protected against voltages higher than 2.5 V. At higher voltages, the measurement circuit is shut off and gives an error
reading. However, if the maximum voltage in the
Data sheet
is exceeded (that is, 36 V), then this input or the equipment may be
damaged.
Current input
The current input may be either active or passive, and a combination of active and passive inputs may be used.
More information
See the
Installation instructions
for more information about wiring details.
Resistance input
The resistance inputs are always passive inputs. The controller sends a small current through the external equipment and measures
the resistance.
