27
Locate the PS unit to be accessible for operator. Connect PS cable to
the card collector board. Connect (+) and (-) contacts of power supply to
(+ 12V) and (GND) contacts on the board respectively (Fig. 13). When the
card collector board is powered, D11 LED indicator will turn on.
Make sure that cable is connected securely.
6.3. Connecting operating device
Connection of OD to the card collector is performed with the use of two
contact sets: "Let Go" and "Pass Ok-GND". Contacts location is shown in
Fig. 13
6.3.1. "Let Go" contact set
NC, NO, and COMM contacts. Relay output operating on a "dry contact"
principle, which closes / opens, transmitting passage authorizing signal to
OD. NC and COMM - normally closed connection, NO and COMM-
normally open connection.
6.3.2. "Pass Ok-GND" contact set
Pass Ok and GND contacts. Pulse input that receives a signal from OD,
confirming that the passage was performed. The operating principle is
based on normally open contacts. Passage is detected by a contact closure
for at least 200 ms.
