Printer Interface Module
The Printer Interface module provides a pre-formatted chiller log to a printer. The Printer
Interface can be programmed via the Clear Language Display to print a chiller log on command,
at the time of a diagnostic, and/or on a periodic basis. Each printed event is time and date
stamped.
The preferred printer to be used is Okidata Microline 184 Turbo. Serial cables required are
(DB25 male to DB9 Female). The maximum distance allowed between the printer module and
the printer is 50 feet.
Secondary Printer Options
Epson: not all Epson printers support serial communications. For a low cost printer that does
support serial communications, Epson recommends the LX810 Printer with the Serial
interface option (C823032).
IBM ProPrinters: Use either the “2380’ + or the “2390+’ along with the Serial interface option
“1363110”.
Other: Any printer/computer with 232 capabilities should be capable interfacing with the TCI
Printer module (allowing for different cables and jumper configurations).
Duplex Control Module (DCM)
Duplex control is accomplished by the Duplex Control module that resides in the downstream
Unit Chiller “A”. It’s tasks are setpoint control (chilled water and current limit) and compressor
staging. All other setpoints are controlled at each individual compressor UCP2 Clear Language
Display panel. Each unit can be reset or stopped separately through each CLD. The dip switch
setting on the board is ON-OFF-ON. IPC communication with the downstream chiller “A” panel
connects to J1, 1 & 2. IPC communication with the upstream chiller “B” panel connects to J3, 1 &
2.
