Power supply - terminal (6):
The 12V power supply can be
unidirectiona
l or
alternate
, the polarity is
unimportant, the maximum off-take from a 12V supply is 250mA.
It is possible to use the power supply to power up an electronic lock, but it
is recommended that 12V/1A is used.
It is also possible to use a
24V unidirectional
power supply. Although it is
mainly used during installation, where there already is a power supply and,
for example, for attendance systems or sliding gates. The motherboard
heating has regulated element with a limited performance, other circuit are
sized for 24V power supply. You cannot use and alternate power (AC)
supply, only unidirectional. Polarity is unimportant.
Supply voltage on the terminal (6) is necessary for the following functions:
- relay control;
- motherboard heating (DIP 2 switches on, regulation of current
according to voltage and temperature);
- name tag back lighting (DIP 5 switches on - only
(C)
, in
(LC)
the
light is constant);
- internal power supply of door entry system electronics (DIP 3
and 4) only
(C)
– replaces Best Box (solution for switchboard
Siemens). If there is a constant power supply, it is possible to
carry on relay regimes 7 and 8 (be careful about parameter 64);
and
- powering up the exit button circuit, only on
(C).
Exit button
–terminal (8) – only
(C)
:
The exit button is used for a direct relay control. On each relay it is
possible to set up a switch on one or on two impulses. Button (terminal
(8)) is connected in a current loop circuit powered up from a 12V (terminal
(6)). It is possible to connect it with a cable as long as 500m.
Peripheral Component Interconnect (PCI) for extra buttons:
This PCI enables you to connect additional buttons (up to 99) including a
keyboard. Apart from the series data the PCI also contains a power
supply for the nametag back lighting. Each button module can process up
to 8 buttons (the
BSC-mod4
contains 4 buttons and you can connect
another 4 buttons with the
BSM-mod4
). It is also possible to connect a
keyboard in place 1
– 8 on the PCI, additional buttons can also be added
after that. To simplify a place can be determined as
– how many flat
cables are between the keyboard and the motherboard, which is where
the keyboard is connected.
