Note
: To realize the Serie 60 door panel replacement to Nexa 60, follow the steps described in the
manual '
Nexa 60 replacement
' that it is supplied with door panel (aluminium modules).
Note
: Replace the installation of several access Serie 60 '4+n' to Nexa 60 '4+n'. If telephones are not
compatible with electronic call they must be also replaced by Golmar electronic call-compatible
telephones. For the connection of the Nexa 60 '4+n', (see pages 55-56).
Important
: If the installation transformer is replaced (A-100, A-104, A-105, A-120 and A-124) with
TF-104, the wire connected to terminal 3 must be annulled from replaced transformer.

TROUBLESHOOTING HINTS
O
Nothing operates.
w
Check the output transformer voltage between 'SEC' terminals: it should have 12 to 17Va.c. If not,
disconnect the transformer from the installation and measure again. If it's correct now, it means
there is a short circuit in the installation. Disconnect the transformer from mains and check the
installation.
O
Inappropriate audio level.
w
Adjust the level volumes as shown on page 50. In case of feedback, reduce the audio levels until
feedback fade out.
O
Door open function no operates.
w
Disconnect the lock release from the sound module EL651 and short-circuit terminals 'CV' and 'CV':
at that moment the output voltage between terminals 'CV' and '~2' should be 12Va.c. If it's so
check the lock release, its wiring and the wiring of the terminal 'P1' from the sound module to the
telephones. If these tests don't solve the problem, replace the sound module.
O
No telephones receive the call or acknowledgement call signal is not reproduced.
w
Check push buttons wiring (page 48) and the connection cable between modules are well connected in
the push buttons connector (page 49).
O
Busy channel no operates.
w
Check when a call is made on one of the door panels, the voltage between the terminals '-' and 'CO'
of all door panels is less than 3Vd.c. If not, check the continuity of the 'CO' wire.
w
Remember: Door open function is only active during call and communication progresses.
