Danfoss VLT HVAC Drive FC 102 Operating Instructions Manual page 29

Mechanical Installation
30 Amp, 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 is
provided from the load side of any supplied
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 3rd party 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
Designed for monitoring temperatures of external system
components, such as the motor windings and/or bearings.
Includes 8 universal input modules plus 2 dedicated
thermistor input modules. All 10 modules are integrated
into the frequency converter's STO circuit and can be
monitored via a fieldbus network (requires a separate
module/bus coupler).
Universal inputs (8) - signal types
•
RTD inputs (including Pt100), 3-wire or 4-wire
•
Thermocoupler
•
Analog current or analog voltage
Additional 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
Dedicated thermistor inputs (2) - features
•
Each module is capable of monitoring up to 6
thermistors in series.
•
Fault diagnostics for wire breakage or short-
circuits of sensor leads.
•
ATEX/UL/CSA certification
•
A 3rd thermistor input can be provided by the
PTC Thermistor Option Card MCB 112, if
necessary.
