TESTING
After completing the wiring, use a continuity tester to check that the wiring are properly done and the unit
is ready for testing. IMPORTANT NOTICE; it is of the assumption that the testing in done in the factory
and not at site where wirings are connected and the gen-set ready to start.
It should be noted that the DAMF-5 is designed for both 12VDC and 24VDC. Do Not feed 240VAC
mains supply into any part of the unit as it will definitely be damaged. All the DAMF-5 outputs are open
collector type, Do Not connect a positive source direct to them, always connect in series relays, bell or
lamps from source before connecting to the output. As the testing process is long, it is broken into steps,
at any time feel free to repeat the steps, as follows:
1) Check Voltage
Check the charger and battery voltage. It should be around 27VDC or 13.5VDC depending on the
battery type used. Both voltage is suitable as an auxiliary power source. Do Not use a power source
that is between 15VDC and 20VDC. It is not healthy for the DAMF-5 and may cause damage. If an
18VDC source is connected, it will select 12VDC power input and that is 150% higher. The
internal relay will overheat and fail after prolong period.
2) Switch On
Select to Off mode and switch on the circuit breaker. Notice that the display shows
H H H
for one
second before displaying
OFF
. Confirm that the supply voltage LED correspond with the auxiliary
voltage.
3) Emergency Stop
Press the emergency stop button. The display should goes off and the Energize Stop LED lighted. If
in use, check that the Energize Stop relay energizes. Wait for about 45 seconds until the LED goes
off and the relay de-energizes. All other relays or lamps should be off but the supply LED remain
lighted. This confirms the Emergency Stop is functioning. Reset the button to continue.
4) View Default Settings
Remain in the Off mode, press and release the
MFB
button to view the parameter settings. Repeat
to toggle through the range of parameters. The display flashes between the parameter and its value
at half second interval. 10 seconds of inactivity at any stage reverts the display back to
OFF
. The
range of parameters and default value should be as follows;
SFC
- 1,
SFt
- 5,
Crt
- 6,
rSt
- 10,
Att
- 6,
OPt
- 10,
Sdt
- 120,
ESt
- 10,
LFL
- 0 and
OFF
.
5) Change Default Parameter Settings.
Remain in the Off mode, press and release the
SET
button. When the display shows
SEt
, press and
releases the
MFB
button and repeat to toggle to the desired parameter. Then press and HOLD the
MFB
button, when the desired value is shown, quickly releases the button. Repeat the process to
change the next parameter or wait 10 seconds and the new value will be burn into the memory.
During the burning process display shows
- - -
. Burning is complete when display shows
OFF
.
View the parameters again to confirm the new settings.
6) Lamp Test
Select to Automatic mode and the display shows
Aut
. Press and HOLD the
MFB
button, the
display should show
LPt
and all the fault lamps lighted. Release the button and display reverts
back to
Au
t and all fault lamps off. Repeat if desired. The only time you can perform lamp test is in
the Automatic mode.
