Troubleshooting Hints - golmar V2PLUS Manuel D'installation

TROUBLESHOOTING HINTS

An easy way to check that the system is working properly is to disconnect the wiring from the door panel
and to check the monitor directly connected to the EL500/V2Plus circuit
A short circuit between different terminals of the installation will never damage the connected systems
Nothing operates
Remember that the system remains inactive for 45 seconds after connecting the power supply,
the same occurs upon connecting any unit to the installation
Check that the power supply's output voltage between the –
not, disconnect the power supply from the installation and measure again If it's correct now,
it means there is a short circuit in the installation Disconnect the power supply from mains
and check the installation
With system in rest, check the voltage between
microprocessor module is from 23Vdc to 25,5 Vdc
verify there is not a short circuit or anomaly
If these tests don't solve the problem, check the voltage between the
EL500/V2Plus
EL500/V2Plus
If the previous verifications are correct then check the autodiagnostic LEDs (see page 92)
Inappropriate audio level
Adjust the audio levels as shown on page 93
Audio feedback
Lower the volume of the sound module, using as well, the potentiometer located in the
EL500/V2Plus
If feedback doesn't disappear refer to the following hint
Continuous audio feedback
Check for short circuits in the BUS itself or between the BUS and any other terminal.
Door open function don't work
Remember that this function is only available during call and communication progresses
Create a short circuit between the
microprocessor module; once done, there should be 12 Vd.c. between the lock release
terminals If so, check the lock release and its wiring
The system cannot be programmed
Check that the switch number 2 of the configuration dip switch is set to ON (see page 92) and
that the programming steps are correctly followed
Check the autodiagnostic LEDs of the EL500/V2Plus microprocessor module (see page 92)
Some units don't receive calls
Remember that each apartment must have only one terminal programmed as master Check
that the terminal is correctly programmed; if necessary, program it again
Some monitors are not OK the image.
Check in the monitor the Sw2
Push buttons don't work
When the push button is pressed check that the door panel reproduce a confirmation tone; if
not, check the wiring of the push buttons (pages 89 and 90)
If there is a confirmation tone, check the programming of the monitors (page 99) and the
telephones (page 102).
