3.2.16 FREQUENCY READING BY GENERATOR SET OT PICK-UP (GEN/PCK)
(READING ONLY. SELECTION BY MICROSWITCH 2)
Indicates whether the speed is controlled by generator set (microswitch 2 OFF) or
by the Pick-Up (microswitch 2 ON).
NOTE
It is very important to connect only one of the two frequency reading inputs. In
other words, if you connect the phase and the neutral of the alternator to the
generator’s control unit input, you cannot connect the wires of the Pick-Up to the
corresponding input and vice versa, under any circumstances.
3.2.17 ENABLING THE OVERSPEED THRESHOLD.
Enables or disables the overspeed control.
NOTE
When you disable the overspeed threshold, the stored rated frequency, if it
exists, will not be deleted and detection of start-up by frequency threshold will
continue to be enabled. If you want to delay the detection of start-up by speed,
you will have to increase the start-up detection frequency threshold.
3.2.18 ENGINE SHUTDOWN BY FUEL RESERVE (RC) - ALARM / SHUTDOWN
Allows you to select the action to be performed after the fuel reserve alarm has
been detected. If you select the "ON” option, when the alarm is detected, it acti-
vates the corresponding optical indicator and it starts a shutdown without cool-
ing cycle. In the "OFF" position, it only indicates the alarm by the optical signal
but it does not stop the group.
3.2.19 PREHEATING ENABLING (READING ONLY. SELECTION BY MICROSWITCH 4)
Enables or disables the preheating. If disabled (OFF), the duration of the preheat-
ing will be the "SPARK PLUG PREHEATING TIME” parameter, which by default is
zero. If it is enabled (ON), the preheating time is determined by microswitch 1
which chooses between short preheating (5 seconds) or a long one
(10 seconds).
If no rated frequency has been stored. The genset will be deemed to have start-
ed as of 20 Hz if the frequency reading by generator set option has been
selected.
3.2.12 THRESHOLD FOR OVER-FREQUENCY DETECTION
Percentage increase of the scheduled frequency above which it will be consid-
ered overspeeding.
3.2.13 ALARM OUTPUT ACTIVATION TIME
Indicates the time that the alarm output will be active. If it is set to zero, the out-
put will remain active indenitely until you press reset or you turn off the control
unit.
3.2.14 D+ TIME
Excitation time of the battery charging alternator (Always less than the starting
time).
3.2.15 ENGINE CONFIGURATION (READING ONLY. CONFIGURED BY
MICROSWITCHES 7 AND 8)
Engine (PR/PD) with preheating and stop by de-excitation provided through the
congurable stop output (Microswitch 7 OFF and Microswitch 8 OFF).
Engine (PR/PE) with preheating and stop by excitation at the congurable stop
output (Microswitch 7 OFF and Microswitch 8 ON).
Engine (PR/PE) with stop by excitation at the preheating output and stop by
de-excitation at the congurable stop output (Microswitch 7 ON and Microswitch
8 OFF).
Engine (PR/PULL) with preheating, PULL type start-up (1 press of 1 second) and
HOLD type stop provided through the PD Output (Microswitch 7 ON and Mi-
croswitch 8 ON).
