GEXD (Generator Exercise)
To prevent the generator from seizing up, it
is good practice to exercise the generator
periodically. The PL supports this with an
automatic generator exercise function, which will
turn on every GEXD days at 9am. The number
of days since the last exercise is shown on the
GDAY screen. The generator will run for GRUN
hours. When running, the elapsed time is shown
on the GTIM screen. Both GDAY and GTIM can
be adjusted.
Note:
1. There is no generator exercise when GMOD = 3
(manual start).
2. GSET toggle does not work during generator
exercise
3. A small amount of overcharge will occur if
battery is already fully charged. Use a low GRUN
value if this is of concern.
GDEL (Generator changeover delay)
A programmable delay (in minutes) is used to
prevent any large transient loads from triggering
a generator change of state (on/off). Default
programs are set to 10 minutes.
Note:
Do not confuse GSET (CHRG menu) and
LSET (LOAD menu) with screens of the same
name in the SET/MODE menu. They perform
different functions.
Generator Example
The generic programs (PROG=0-3) use
voltage driven generator control (GMOD=0).
See “settings used in Programs 0-3” for on-off
voltages etc.
If you want something different, eg SOC%-
triggered generator on, voltage-triggered
generator off, and no quiet time, you would set
up the PL as follows:
PROG = 4
Allows changing of generator
functions etc
GMOD =
5
SOC % ON
, Voltage OFF,
no quiet time
CHRG menu:
Set GON, GOFF, GDEL, SOC%
GEXD, GRUN as required
SET/REG menu: Check these settings are
correct for your battery type
SET/MODE menu:
LSET = 2
or
GSET = 2
LSET if using LOAD - terminal
for relay
GSET if using ‘G‘ terminal for
relay
