Danfoss VLT HVAC Drive FC 102 Operating Instructions Manual page 37

Mechanical Installation
starters are allowed (one if a 30 A, fuse-protected circuit is
ordered). The motor starters are integrated into the
frequency converter's safe-stop circuit.
Unit features include:
•
Operation switch (on/off).
•
Short circuit and overload protection with test
function.
•
Manual reset function.
30 A, fuse-protected terminals
•
3-phase power matching incoming mains voltage
for powering auxiliary customer equipment.
•
Not available if 2 manual motor starters are
selected.
•
Terminals are off when the incoming power to
the frequency converter is off.
•
Power for the fused protected terminals are
provided from the load side of any supplied
contactor, circuit breaker, or disconnect switch.
24 V DC power supply
•
5 A, 120 W, 24 V DC.
•
Protected against output overcurrent, overload,
short circuits, and overtemperature.
•
For powering customer-supplied accessory
devices such as sensors, PLC I/O, contactors,
temperature probes, indicator lights, and/or other
electronic hardware.
•
Diagnostics include a dry DC-ok contact, a green
DC-ok LED, and a red overload LED.
External temperature monitoring
External temperature monitoring, designed for monitoring
temperatures of external system components, such as the
motor windings and/or bearings. It includes 5 universal
input modules. The modules are integrated into the
frequency converter's safe-stop circuit and can be
monitored via a fieldbus network (requires the purchase of
a separate module/bus coupler).
Universal inputs (5)
Signal types:
•
RTD inputs (including PT100), 3-wire or 4-wire.
•
Thermocouple.
•
Analog current or analog voltage.
Extra features:
•
1 universal output, configurable for analog
voltage or analog current.
•
2 output relays (N.O.).
•
Dual-line LC display and LED diagnostics.
•
Sensor lead wire break, short circuit, and incorrect
polarity detection.
•
Interface set-up software.
