Remote Interfaces            

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 485/232  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 PANEL 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.  Note: Placing the controller into RMT PANEL essentially locks out all front panel commands.

RMT RELAY is the remote mode used for monitoring and controlling the system via dry contact closures.  The remote indicator outputs are available on the remote RELAY port at all times.  There are remote indicators for all faults and mode settings.  The RMT RELAY command inputs are only recognized by the controller while the controller is in the RMT RELAY 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 are needed on the switch in order for them to be transferred over to the Remote Standard port.  See pins J1-6,7,8, J2-6,7,8 on rear chassis.

All indicators on the Remote Relay port are form A relays, or Normally Open.
