Assembly & Operation Manual

The ACS controller inputs are connected to the contacts
Common
,
PASS A
,
PASS B
of
the
XS1
connector block and to the contacts
Ready
and
Det Out
of the
XT1.H
connector
block.
Pin assignments of the connector blocks are given in Fig. 13.
5.4 Additional devices connectable to the turnstile
5.4.1
Relay outputs
Connection of control board to relay outputs is done through corresponding contacts of
connector block
XT1.H
. The following relay outputs are installed:
•
ALARM:
contacts
Alarm 1
and
Alarm 2
(see Clause 5.4.2),
•
PASS A:
contacts
Pass A
and
Common
(see Clause 5.2.7),
•
PASS B:
contacts
Pass B
and
Common
(see Clause 5.2.7),
•
READY:
contacts
Ready
and
Common
(see Clause 5.5),
•
DETECTOR:
contacts
Det Out
and
Common
(see Clause 5.4.2).
Contacts
Pass A
,
Pass B
and
Common
are also located on connector block
XS1
.
Relays have normally open contacts. Therewith common for those relays contact
Common
is not connected with the negative of turnstile power supply (galvanically isolated). In initial
(standard) condition with a switched on power supply relay contacts
PASS A
,
PASS B
,
READY
and
DETECTOR
are closed (relay coil gets energized), and relay contacts
ALARM
are opened (relay coil gets deenergized).
Relay winding energizing can be identified by lighting up of corresponding red LED,
installed on control board near the corresponding relay (see Fig. 5).
Figure 9 – Output cascades for PASS A, PASS B, Ready, Det Out and Alarm
The output cascades for
PASS A
,
PASS B
,
Ready
,
Det Out
and
Alarm
are the contacts
with the following signal characteristics (Fig. 9):
maximum commutation voltage ...................................................................... 42 VDC
maximum switched current ............................................................................... 0.25 A
closed contact resistance ...................................................... no more than 0.15 Ohm
