Troubleshooting Hints - golmar VistaPlus Manuel D'installation

A n 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/R5 circuit.
A short circuit between different terminals of the installation will never damage the connected
systems.
Nothing operates.
O
Remember that the system remains inactive for 45 seconds after connecting the power
w
supply, the same occurs upon connecting any unit to the installation.
Check the output power supply voltage between ' - ' and '+' terminals: it should have 17,5
w
to 18,5Vd.c. If 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.
Check that 'A/D' terminal is not shortcircuited with ' - ' or '+' terminals.
w
If these tests don't solve the problem, check the voltage between 'B' and 'CP' terminals of the
w
EL500/R5 circuit; if the measured voltage is different to 12Vd.c. change the EL500/R5
circuit.
Inappropriate audio level.
O
Adjust the level volumes as shown on page 109. In case of feedback, reduce the audio
w
levels until feedback fade out. If feedback doesn't disappear refer to the following hint.
Continuous audio feedback.
O
Check that 'A/D' terminal is not shortcircuited with other terminals.
w
Door open function no operates.
O
Remember that this function is only available during call and communication progresses.
w
The CV1 and CV2 terminals for door opening are voltage free outputs. The cable requires
w
a connection depending on whether 12Vdc or 12Vac is needed, as shown on page
141.
Make a short circuit between the 'CV1' and 'CV2' terminals on the EL500/R5
w
microprocessor circuit; there should be12V (d.c. or a.c. depending on the type door
release installed) between the terminals on the door release. If so, check the lock
release and its wiring.
The system cannot be programmed.
O
Check that the switch number 2 of the configuration dip switch is set to ON (see page 108)
w
and that the programming steps are correctly followed.
Check that 'A/D' terminal is not shortcircuited with other terminals.
w
Some units don't receive calls.
O
Remember that each apartment must have a master unit only. Check that the units are
w
switched on and correctly programmed.
No video image.
O
Check that telecamera's protective cover is not on the EL-531 sound module.
w
Check that dip switch 4 on the EL 500/R5 module is set to ON.
w
Check that power is reaching the distributors, the voltage between the '+' and '-' terminals
w
must be between 15 to 18Vd.c.
Push buttons don't work.
O
When the push button is pressed check that the door panel emits a confirmation tone, if
w
not, check the wiring of the push buttons (pages 105 to 106).
If there is a confirmation tone, check the programming of the monitors or telephones
w
(pages 115 and 118).
