11.6 Function setting menu
This menu allows you to define allocation of the external input of the mother board. It depends if
you are using the master clock as master or slave unit.
If the master clock is used as a master, the external input will, for example, control circuitry to
drive an alarm or buzzer.
If the master clock is used as a slave, the external input (terminals 20 and 21) will detect
changes in the alarm output of the master clock used as master.
It can also be used to activate the backlight of the display screen.
To go to the Sigma C function setting menu, validate the
option in the technician menu with the
The following screen is displayed :
The master clock is configured in master mode by default.
If you configure it in "BACK-UP" (slave) mode to assign it
as a secondary master clock, then the external input (see
below) displays BACK-UP and cannot be modified.
Select a circuit for the external input; the relays proposed
are the relays which have been assigned.
In general, the external input will control a circuit dedicated
to this alarm ringing function, relay ON ....
A contact connected to the external input can also control
simultaneously several circuits. The circuits to be controlled must be specified in the PC
software. Example: Circuit 1 + Circuit 2 + Circuit 60 + Circuit 13.
Choosing the mode (START, LENGTH or FORCED ON) allows you to configure the input for its
functioning and the period of functioning in this state.
START: starts the programming of the circuit concerned the
first time it is pressed and stops it the next time (alarm type
message on the display indicating the external input (circuit
1) and its status (ON, OFF or START).
LENGTH starts the relay in ON mode during the
programming period HH MM SS. Pressing Enter puts
the circuit in stop mode.
FORCED ON: forces the relay position whatever the
programming (as in test mode); 1st pressing ON, 2nd
pressing OFF.
A switch can be placed on the output to configure the status
of the input as ON or OFF permanently.
The following screen can be used to activate or
deactivate the idle screen backlight (by default, the
32
backlight is lit, therefore the value is set to No).
