In order to cancel an alarm, wait until the end of the stop cycle, and turn the KEY to OFF.
A detailed description of each alarm follows.
(**) In NFPA-20 mode the engine shuts down only in case of: EMERGENCY, OVERSPEED and Fail to Start
5.01 ALARM 1
The alarm energises when the JF1 terminal input is grounded. The alarm will be ignored for 10 seconds from
the starting of the engine. The alarm is indicated by red LED on the front panel (see 3.07) and by the message
[AL.1] on the display. To clear the alarm turn the Key-switch in OFF. The alarm can shut down the engine
according to parameter ‘L’
(see section 8.0). In NFPA-20 Mode, the engine cannot be shut down.
5.02 OVERSPEED
The engine shuts down immediately if the JF2 terminal input is grounded. The alarm is indicated by means of
a red LED on the front panel (see 3.07), and by the message [O.SP] on the display. To clear the alarm, turn the
KEY-SWITCH to OFF. The alarm status is repeated on the static output JB4.
5.03 TEMPERATURE CHANNEL 1
This alarm energises if the JF3 terminal input is activated. The alarm is indicated by a red LED on the front
panel (see 3.07), the message [ °C] on the display, and by the output JB8. The contact switch is ignored during
the starting sequence (parameter '2',see section 8.0). To clear the alarm, turn the Key-Switch to OFF. The alarm
can shut down the engine according to parameter
[
L.xx]
(see section 8.0).
In NFPA-20 Mode, the engine cannot
shut down. The polarity of the contact can be selected by the parameter [I.00] (see section 8.0).
5.04 BATTERY 1 - 2 FAILURE
In case of failure of the battery set 1 or 2, the BE26A indicates the message [bt.1] and [bt.2] on the display. The
BE26A does not shut down the engine. If the battery returns within the operating limits
The Be26A removes the message from the display.
5.05 LOW LEVEL FUEL
This alarm is indicated by means of a yellow LED on the front panel (see 3.07). The engine does not shut
down in NFPA-20 Mode. To clear the alarm, turn the KEY-SWITCH to OFF. The alarm status is repeated on the
static output JB6. In engine protection mode the engine shuts down after a delay of 5 minutes. The display will
indicate the message [FUE], and the red LED 'NO FUEL ' will energise.
