3.5.4 Simple test
AGC 100 will go through the start sequence and run the engine for the time set in parameter 7042 without
any breaker operation. This sequence is initiated by a digital input or the TEST push-button on the front. The
test will run until the timer expires. When the timer runs out, the stop sequence including cooling down will be
carried out.
If the timer in parameter 7042 is set to 0, the test is infinite. The test will be interrupted if the mode is changed
to either manual, semi-auto or auto.
3.5.5 Full test
The full test will start the genset, open the mains breaker and close the generator breaker. When the test tim-
er expires or the test is cancelled by mode change, the generator breaker is opened, the mains breaker
closed, and the generator is stopped after the cool-down time.
To run the full test, it is required that AGC 100 is in AMF or load takeover mode.
It is possible to open and close the generator breaker and the mains breaker in manual mode.
3.5.6 Block mode
Block mode can be enabled by pressing the MAN button twice, with M-Logic or a digital input. When block
mode is selected, the controller will be locked for certain actions. This means that it cannot start the genset or
perform any breaker operations from the buttons.
The purpose of the block mode is to make sure that the genset does not start for instance during mainte-
nance work.
It is important to know that the digital input configured to block mode is a constant signal. So,
when it is ON, the unit is in a blocked state, and when it is OFF, it returns to the mode it was in
before block mode was selected.
When controller goes into block mode, it will:
● Open GB, shut down the engine, show "BLOCK" in the display and flash the MAN LED
● GB ON, GB OFF, MB ON, MB OFF and START buttons are locked
If block mode is selected using the display, the block mode can only be deactivated from the display. If block
mode is selected using the digital input, the block mode can only be deactivated by setting the digital input to
OFF.
Before the running mode is changed, it is important to check that persons are clear of the gen-
set and that the genset is ready for operation.
Alarms are not influenced by block mode selection.
The genset can be started from the local engine control panel, if such is installed. Therefore,
DEIF recommends avoiding local cranking and starting of the genset.
The genset will shut down if block mode is selected while the genset is running.
