P17 - MISCELLANEOUS UoM Default Range
P17.01 Maintenance interval h OFF OFF/1-99999
P17.02 Rental hours pre-set h OFF OFF/1-99999
P17.03 Maximum kVA alarm threshold % OFF OFF/5-250
P17.04 Maximum kVA alarm delay sec 0 0-9999
P17.05 Generator switch feedback delay sec 5 1-60
P17.01 – This defines the programmed maintenance interval, expressed in hours. If set to OFF, the maintenance interval is deactivated.
P17.02 – Number of rental hours to be pre-set in counter by command C05 Rental hours pre-set.
P17.03…P17.04 – Threshold and delay for alarm A34 Generator kVA threshold exceeded.
P17.05 – Delay for A36 alarm.
P18 – USER ALARMS
(UAn, n=1…2) UoM Default Range
P18.n.01 Alarm source OFF OFF
INPx
OUTx
P18.n.02 Channel no. (x) 1 OFF / 1…99
P18.n.03 Text UAn (text - 16 characters)
Note: This menu is divided into 2 sections for defining user alarms UA1 and UA2.
P18.n.01
– Defines the digital input or internal variable the activation of which generates the user alarm.
P18.n.02 – Number of channel referred to the previous parameter.
P18.n.03 – Free text that will appear in the alarm window.
Example: User alarm UA2 must be generated by the closing of input INP5 and must display the ‘Doors open’ message.
In the case, set menu section 2 (for alarm UA2) as follows:
P18.2.01 = INPx
P18.2.02 = 5
P18.2.03 = ‘Doors open’
Programmable input functions
Function Description
Disabled Input disabled.
Configurable Freely configurable by the user.
Oil pressure Digital sensor for low engine oil pressure.
Engine temperature Digital sensor for maximum engine coolant temperature
Fuel level Digital sensor for low fuel level
Emergency stop When open, generates A23 Emergencyy stop alarm. Not needed if +COM1 is used with incorporated input.
Remote stop Stops engine from remote point.
Off load remote start Starts the engine remotely without transferring load to the generator. The signal must be maintained for as long as
the engine needs to run. On deactivation of the signal, the engine begins its stop cycle.
On load remote start Starts the engine remotely and connects load to the generator. The signal must be maintained for as long as the
engine needs to run. On deactivation of the signal, the engine begins its stop cycle.
Start without stop Starts the engine remotely and does not stop it in the event of an alarm. The signal must be maintained for as long
as the engine needs to run. On deactivation of the signal, the engine begins its stop cycle.
Generator protection Generator protection tripped signal from external device.
Remote control lock Locks control and write operations via serial port. Data reading remains possible.
Setup lock Prevents access to the programming (setup) menu.
External GEN control Generator voltage control signal from external device. If active, indicates voltage within thresholds.
Enabling of load transfer to generator OK to transfer load to generator.
GEN switch feedback Alarm A36 Generator switch fault is generated in the event of discrepancy between the control output and the
actual state.
Keypad lock Locks functioning of front panel, excluding page navigation buttons.
Genset and keypad lock Locks functioning of the generating set and keypad.
Radiator coolant level Alarm A40 Radiator coolant low is generated when input is activated. .
Siren OFF Disables the siren.
Breaker state alarm With the input OFF, starting is prevented and alarm A41 Breaker closed is triggered. This function is used in
manual control mode when the generator's remote breaker is not used and a manually operated breaker is used
instead. This function is needed to be sure that no load is connected before the generator starts. In AUT mode,
when the input is ON, starting is prevented and alarm
A42 Breaker open is activated. This function is needed to
avoid starting the generator and wasting fuel without a load.
Alarm inhibit When active, disables alarms for which the Inhibit property is active.
Reset alarms Resets retaining alarms the cause of which has ceased.
Commands menu C(xx) Executes the command defined by the index parameter (xx).
Simulate STOP button Closing the input is equivalent to pressing the button.
Simulate START button Closing the input is equivalent to pressing the button.
Configuration selection Selects one of the two possible configurations. See menu P04 Multiple configurations .
Water in fuel Generates alarm A47 Water in fuel.
Programmable output functions
Function Description
Disabled Output disabled.
Configurable Freely configurable by the user.
Close generator switch Close generator remote switch command.
