Note: The LED
TEST switch is a pushbutton type.
The AUTO/MANUAL,
REMOTE/LOCAL switches are mom-off-mom type.
The AUDIO mute
switch is on-off
The controller
has 3 remote modes available to the user.
In order to avoid conflicts, these control
points (Remote/Local modes) are selectable only
from the local front panel. The REMOTE 232/485
mode is used for the available computer
interface. RS232, and RS485 are dip switch
selectable within the control unit. Other
protocol criteria, such as, Address, baud rates,
CR,LF, ignoring checksum errors, and parity
settings are also dip switch selectable. (see
documentation for further detail).
Protocol
REMOTE 422 is the
remote mode setting used for the optional remote
panel. The remote panel is identical to
the local panel, with all of its indicators and
functionality, with the exception of being able
to choose between the Local/Remote modes of
operation. The remote panel is connected
to the local rear chassis via a 6 conductor
cable. It is recommended that a shielded
cable be used, with the shield tied to chassis
ground. The remote unit may be placed up
to 4000 feet away from the local unit.
RMT STD is the
remote mode used for monitoring and controlling
the system via dry contact closures. The
remote indicator outputs are available on the
remote STD port at all times. There are
remote indicators for all faults and mode
settings. The RMT STD command inputs are
only recognized by the controller while the
controller is in the RMT STD mode of operation.
A command input thru this port is entered by
temporarily connecting the command with the
command common for approximately 50 mSec.
Important note on
remote switch position indicators:
The switch
position indicators are taken off of the switch
itself. A second set of indicators is
needed on the switch in order for them to be
transferred over to the Remote Standard port.
See pins J1-6,7,8 on rear chassis.
All indicators on
the Remote Standard port are form A relays, or
Normally Open.
