OPERATION
4.1
General
The GV4 Scalino is operational after full installation and filling
up with fuel and engine lubricating oil; and subsequently
connecting the battery and digital remote control panel.
Fill with lubricating oil twice to allow the heat exchanger to get
filled with oil. This is done by filling up with oil first, run for 60
seconds, and then stop the engine and fill up again.
When checking the oil level inside the lubricating oil reservoir,
simply dip the dipstick into the oil without screwing the dipstick
into the sump.

ADJUSTING GENERATOR FREQUENCY
The Scalino operates on fixed speed setting. Use the speed
regulator (refer to Figure 7) to manually adjust speed within
speed ranges as documented in the specifications. Untighten
the regulator, move downward to adjust speed and tighten
again. Make sure the PMG input voltage is not exceeded when
increasing the engine speed.

Optional variable speed mode
Realize variable speed operation by adapting ECU settings to
the load on the WP-PMG.
In variable speed mode the engine will start when the starting
button is pushed. The speed will adapt to the load. When an
additional load will be switched on the engine will speed up. To
avoid that the engine will not provide enough power to speed
up while a new heavy load is added, the Minimal Engine Speed
has to be set to a minimum (worst case) level from which the
engine will be able to speed up again.
Example: When the engine is running at no load (or almost no
load at 2500 rpm) and a 3 kW load (e.g. an air-conditioner) with
an inrush current for motor starting of 4 x nominal power is
switched on, the engine will probably not be able to ramp up
the rpm. In this case the low speed setting has to be higher;
possibly 2800 rpm. However when load steps of only 1 kW are
switched on, one after another, a low speed setting at 2500
rpm will be OK. The optimal low rpm setting can be established
by trial and error and can be mechanically adjusted on the
engine. However, the PMG’s maximum input voltage shall not
be exceeded.

Operating instructions
While in operation, monitor the Scalino AC load and voltage by
means of the PMG panel LED indicators.

Summarized operating instructions (daily use)
“PRE-START” CHECKS
Perform the following routine "pre-start" checks prior to
starting the WP-GV4 Scalino
:
1
Check oil level
The GV4 Scalino Genverter switches off in the event of
insufficient oil pressure.
Even when the oil level is too low, the oil pressure can
be high enough not to trip an alarm. Do not run the
engine with the oil below the lowest mark, because a
smaller volume of oil will become contaminated
considerably quicker than a larger volume. Also the
cooling can be affected. Therefore we recommend
daily oil-checks.
Check oil level prior to starting the engine or at least 5
minutes after the engine has stopped.
2
Check for leakages.
3
Switch to power source selector switch to "OFF",
or switch off all consumers in the usual way.
4
Switch on the battery switch (when installed).
5
Make sure the fuel valve is open.
