Testing Insulation Monitoring / Startup / Device Connection - Bottarini GDP21 Maintenance And Operating Manual

11. Generator option
3.
Note that the starting consumption of
devices driven by electric engines is
generally a multiple of the specified
rating. If in doubt, it is advisable to
contact the equipment manufacturer
directly.
The maximum current specified for each
socket must not be exceeded.
If normal cooling cannot be maintained,
or the operating conditions are
unacceptable in other respects, reduce
the consumption, rather than operating
the generator right up to its rating.
Ideal operating conditions are:
1. Ambient temperature:
2. Air pressure: 100 kPa (1 bar)
3. Relative humidity:
Do not operate the generator at ambient
temperatures above 40 °C, below –10 °C,
or in direct sunlight.
More detailed instructions for operation
under unfavourable conditions can be
found in the combustion engine manual.
11.5 Testing insulation monitoring /
startup / device connection
Testing insulation monitoring
Attention
Do not start the generator until you
have fully read and thoroughly
understood the safety precautions and
operating instructions in this manual.
During operation, check at least once a
day that the protective measure for the
risk of electric shock through indirect
contact (in accordance with DIN and
GW 308 requirement for Protective
isolation with insulation monitoring
and circuit breaking) is working
properly
With the engine running, carry out the
following test:
1.
Unplug all devices connected to the
generator; open the glass cover and
switch the circuit breaker to ON/I.
2.
Press the test button (red or blue).
3. Check whether the circuit breaker
releases and red the INSULATION
FAULT indicator lamp lights up.
4.
Switch the circuit breaker to ON/I; close
the glass cover (tighten the knurled
screws by hand); the generator is now
ready for use.
Attention
The generator may only be used if the
circuit breaker released during the test
and the red indicator lamp came on.

Setting the range switch
Turn the range switch to the required
position:
1st position:
Compressed air and electrical power,
variable engine speed.
* Compressed air and electrical power
can be consumed up to maximum
engine speed.
Note that engine speed is reduced in
the event of an overload.
* Compressed air mode without
consumption of electric power:
–> engine speed matched to demand
25 °C
* Additional consumption of electric
30%
power: –> variable engine speed is
matched to consumption automatically,
up to maximum speed
* Automatic no-load operation, i.e. the
engine continues to run at maximum
speed for 100 seconds, if the electrical
power consumption is less than 75 VA
for a brief period.
2nd position:
As 1st position, but with the engine
running at constant speed
* Same functions as for 1st position, but
with the engine running at constant,
maximum speed

Danger
Follow safety precautions!
* Carry out the usual checks (safety
precautions, installation location, oil
level, fuel, etc) before using the
machine.
* Ensure that all the devices on the
generator output sockets have been
disconnected.
Note
All device switches must be in the
AUS / 0 / OFF position.
Danger
Unchecked devices may endanger
personnel on startup, and may be
damaged or cause damage.
* Start the generator.
Note
Do not load the generator until the
engine has warmed up.
* Check that the circuit breaker is
engaged in the ON / I position
(close the glass cover).
Fig. 41
Connect the devices to the output
sockets one after the other, ensuring
that the current specified for each
socket is not exceeded, and the
generator is not overloaded.
Note
Turn the devices on, one after the
other, using the device switches.
If possible, plug in/switch on devices
with high startup currents first. Only
connect suitable equipment in perfect
condition to the generator.
Switching off
*
Turn the devices off, one after the
other, using the device switches.
Note
If possible, switch devices with the
highest current consumption off last.
* Switch the devices off one after the
other.
Note
Ensure the covers of unused sockets
are closed again properly.
