terminator
Use boot jumper if controller is not responding to communication (e.g. due to faulty programming
sequence). Take off the rubber cover using screwdriver to acces boot jumper next to dongle slot.
Use 120
Ω
terminators at the end of CAN1, CAN2 or RS485 buses. Do not use these terminators on
units that are not terminating the bus.
Use pull up and pull down resitors on RS485 to bias the line when no device is active on the bus to
prevent noise from undriven line to be interpreted as data.
3.3
Wiring (general)
To ensure proper function:
Use grounding terminals.
Wiring for binary inputs and analog inputs must not be run with power cables.
Analog and binary inputs should use shielded cables, especially when the length is more than
3 m.
Tightening torque, allowable wire size and type, for the Field-Wiring Terminals:
For Mains(Bus) Voltage, Generator Voltage a Current terminals
o
Specified tightening torque is 0,56Nm (5,0 In-lb)
o
Use only diameter 2,0-0,5mm (12-26
AWG) conductor, rated for 90°C
minimum.
