Remote Interface - Process Technology LUFRAN Instruction

REMOTE INTERFACE:

The remote interface is used for communication between the Lufran fluoropolymer inline
water heater and a customer-supplied control device. The remote interface will allow
remote operation of heater start/stop, adjustment of the process setpoint and remote
monitoring of the alarm system. Some of the remote interface inputs have been
jumpered at the factory, to allow for heater operation with the remote interface cable
disconnected. These jumpers are located in the electrical side of the heater cabinet,
and are marked by a red tag. If the customer wants to use the remote interface, these
red tag jumpers must be removed.
The unit must be in REMOTE control mode in order to operate the unit through the
remote interface. However, the various status signal outputs are active when in any
mode of operation. Refer to the CONTROL ACCESS menu listed in the OPERATIONS
section of this manual to change the PLC control system to REMOTE control mode.

If the unit was provided with the optional expanded remote interface (-RI) or a custom
remote interface (-R# at the end of the model number), then refer to the electrical prints
(provided with this manual) for your specific signals and pin-out assignments.
