Terminal Function Description
When the At Fault Close function is selected, the relay is
energized upon fault. The contact returns to its original position
when one of the following occurs:
• The fault has been removed and ASTAT-BP was reset.
• Disconnection of Control Supply
When the At Fault Open function is selected, the relay is
energized immediately when the Control Supply is connected and
de-energizes when one of the following occurs:
• Fault
• Control Supply disconnection
Refer to section 4.7.8 page 39 for PROG. Fault Relay
programming.
Terminal D- RS-485 communication (-) • Standard RS485, half duplex with Modbus protocol, baud rate
1200, 2400, 4800, 9600 BPS.
Terminal D+ RS-485 communication (+) • Twisted shielded pair should be used.
Connect shield to ground on the PLC/Computer side.
Terminal 28 Thermistor input (T1) • Up to 32 units can be connected for Modbus RS485
communication. For reliable communication, units should be
installed in the vicinity of 200m maximum, from the first to the last
unit.
• Refer to section 4.7.9 page 41 for programming.
• Refer to section 8.1 page 59 for wiring diagram and more details.
• Refer to Appendix A of this manual for Modbus protocol manual.
Terminal 29 Thermistor input (T2) Thermistor input is programmable as a PTC or NTC type thermistor.
The trip value is adjustable between 1-10Kohm, preset delay of 2
Sec.
Terminal 30 Ground Connect thermistor and/or Analog output shield to ground terminal.
Terminal 31 Analog output (-) Analog output (0-10VDC or 0-20mA or 4-20mA)
Terminal 32 Analog output (+) Reflects motor current and is related to 2xIm. i.e., Full scale (10VDC
or 20mA) is related to 2xIm.
