Interface mode for porter's exchange
The porter's exchange doesn't receive calls from the door panel.
Check if calls are received from any other telephone (pressing the lock release push button
with the handset off the hook).
If so, check the porter's exchange configuration, verify the option of seizing the panel is active
and that the switch number 3 is set to ON.
If not, check the porter's exchange is not switch off (the screen shows a line of points),
remember the red led is always lighted.
Check the wiring (page 30) and the converter configuration (page 28).
Column encoder mode (General entrance door panels)
Impossible to call from the general entrance door panels.
Check whether it is possible to call from the internal panels.
If so, make sure the programming of the column in the converters has been done
appropriately (page 29) and check the wiring (page 31) and the configuration (page 28).
If not, revise the telephones programming (see the door panel manual) and, if necessary,
repeat the programming steps.
Check also the voltage between the - and + terminals of the several elements is about 17,5
to18,5Vc.c., otherwise, check the power supply and wiring.
The converter can not be programmed.
Check the coded panel is set to the configuration mode before setting the switch number 1 to
ON (see page 28) and that the programming sequence is correct.
Check the BUS terminals are not short-circuited between them nor any other terminal.
Column encoder mode (Coded panel)
Calls can not be done.
Remember that once the power supply is plug in, the system remains inactive for 45 sec,
likewise when connecting any other unit into the installation.
Make sure the converter has not any column programmed, to do it, set the switch number 2 to
OFF and then put it back to its correct position (ON), like this the column programming is
reset.
Review the converter wiring (page 33)and its configuration (page 28).
Check also the voltage between - and + terminals of the several elements is about 17,5 to
18,5Vd.c., otherwise, check the power supply and wiring.
