Hardware architecture TRACER CH532 offers customer the possibility to use inputs or outputs in order to: - use an external water setpoint reset using an analog input (refer to figure 3) - use an auxiliary setpoint - connect a remote on/off of the unit or a circuit - reset faults - connect a remote Cooling/Heating switch - return a circuit fault Note: External water setpoint Based on a external signal input, it will be possible to offset the active setpoint from 0°C to 20°C.
Starting/stopping the unit Once the unit is powered on (main disconnect switch closed) TRACER CH532 returns to the following display: TRACER CH532 01/05/04 Water Temp OFF BY KEYB.

Alarms 1. Alarms display and Resetting A fault on a unit will be shown through the user interface or through 2 digital outputs, one for each refrigerant circuit. The alarms are divided into 3 categories: - Warning. Shows that something is wrong on the unit but unit can be kept in operation. A message is displayed on the user interface screen. These messages are not recorded in the history list.

LonTalk® option Description The Lon interface uses an Echelon FTT-10 transceiver, which is approved to be used on the TP/FT-10 channel.
LonTalk® option LED meaning and function Green Status LED LED status LED is OFF continuously. Meaning/Function • Normal condition • Broken hardware • No power LED is ON.
LonTalk® option Nv1 0=off 1=on nv2 range -12.2°C 48.
LonTalk® option Cable characteristics Level 4 cable may be used with TP/FT-10 channels. The level 4 cable specification used by Echelon and as originally defined by the National Electrical Manufacturers Association (NEMA) differs from the Category 4 specification proposed by the Electronic Industries Association / Telecommunication Industries Association (EIA / TIA). The following specifications can be used by cable suppliers to identify a compliant Level 4 cable.
