6.12.Digital Inputs
• Terminals [ 30 ] through [ 33 ] are all free of voltage.
• 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).
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, dEF = 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 .
6.13.Analog Output
• Can be set between 4 to 20mA and 0 to 10VDC.
• Use a CABCJ15 cable for connections.
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 xx D
or XV xx K.
