Only one controller for each LAN should be connected to the RS485 connection.
The Adr parameter is the number that identifies each electronic board. Address duplication is not permitted; in this case,
synchronized defrost and the communication with the monitoring system are not guaranteed (the Adr is also the MODBUS
address).
5.6. Digital Inputs
The i1P can be set to: cL= active when closed; or oP= active when opened.
The i1F parameter can be set to: EAL = external alarm, Bal = serious lock alarm, PAL= pressure switch alarm, dor = door switch,
dE F= external defrost, AUS= auxiliary activation command, LiG= light activation, OnF = board On/OFF, FHU= do not use this
configuration, ES= day/night, or HdY = do not use this configuration.
The i1d parameter is for the delay of activation.
For the other digital inputs, same set of parameters is present: i2P, i2F, i2d, i3P, i3F, i3d.
5.7. Analog Output
The analog output is located near the terminal [39] on a two-pin connector. The analog output can be used to control anti-sweat
heaters using a chopped phased controller, XRPW500 (500 watt) or family, XV...D or XV...K.

1. Terminals [30] through [33] are all free of voltage.
2. Use a shielded cable for distances higher than one meter.
For each digital input, configure the parameters: i1P (polarity of activation), i1F (function of
the input), and i1d (delay of signaling).
• Can be set between 4 to 20mA and 0 to 10VDC.
• Use a CABCJ15 cable for connections.
