Installation guide

Section 2 - Installation of the Control Panel 27
NOTES:
• Do not short or touch the serial port RS-232 pins with your fingers.
• Prior to connecting the cable, the installer should remove the electrostatic
charge, e.g. by touching a grounded equipment (faucet, heater, etc.). with the
top of his hand.
• It is recommended that the cable be connected first to the control panel
connector, and then to the computer or printer connector.
The control panel RS-232 port also enables the panel to be connected to the
computer. The connection is made in the same way as for the printer (connection of
signals RXD, TXD, DTR and ground). After starting the DLOAD10 proprietary
program (on the included floppy disk), selecting the appropriate communication port
(CONFIGURATION window) and activating the FS-112 service function in the control
panel, it is possible to program the control panel from the computer. Provision is also
made for a service start of the panel, while automatically starting the local
communication mode (for further information see section Starting the Control Panel).
Programming the CA-10 plus control panel through the RS232 serial link should be
carried out by means of a cable identical as for the CA-64 panel (Figure 11). Using
the same cable as for the previous panel (CA-10) may entail some inconvenience:
when the control panel uses the telephone link during a data exchange with the
computer (monitoring, reporting), a message „Attention ! No response from panel”
may appear in the DLOAD10 program. This will not take place when the connection
is made as shown in the illustration above, because the panel, using the additional
RTS cable, will report a temporary break in operation of the RS-232 port.
Connection of Power Supply
The control panel is permanently connected to the mains power supply. Hence,
before you start to work on the system cabling, make yourself familiar with the
electrical installation in the facility. In order to power the control panel, select a circuit
where voltage is always present. This circuit should be protected with an appropriate
fuse.
CAUTION
!
Before connecting the control panel to its power supply circuit, you must turn off
voltage in that circuit.
Description of electrical connections to the CA-10 OBU housing
The AC power supply unit encased in the plastic box is fully electrically isolated
from the metal housing.
• Connect the 230V alternating voltage leads to the transformer terminals
marked "AC 230V".
• Connect the output voltage wires of the transformer secondary winding to the
"AC" (~18V) terminals on the control panel main board.
• Connect the wire of the PE electric shock protection circuit to the terminal
block situated next to the transformer and marked with the ground symbol
.
This circuit should also be connected to the control panel protective terminal.
Do not connect the "neutral" wire of the 230V AC mains supply circuit to the
ground terminal. If there no separate electric shock protection circuit in the facility,
this terminal should be left free.
Control panel power-up starting procedure
1. Connect the emergency power supply wires to the corresponding battery
terminals (the red one to the battery plus, the black one to the minus). The
