IEC Emergency Stop with Pilz Safety Relay
Includes a redundant 4-wire emergency-stop push-button mounted on the front of the enclosure and a Pilz relay that monitors it in conjunction with the
drive's safe-stop circuit and the mains contactor located in the options cabinet.
Manual Motor Starters
Provide 3-phase power for electric blowers often required for larger motors. Power for the starters is provided from the load side of any supplied contactor,
circuit breaker, or disconnect switch. Power is fused before each motor starter, and is off when the incoming power to the drive is off. Up to two starters
are allowed (one if a 30A, fuse-protected circuit is ordered). Integrated into the drive's safe-stop circuit.
Unit features include:
•
Operation switch (on/off)
•
Short-circuit and overload protection with test function
•
Manual reset function
30 Ampere, Fuse-Protected Terminals
•
3-phase power matching incoming mains voltage for powering auxiliary customer equipment
•
Not available if two manual motor starters are selected
•
Terminals are off when the incoming power to the drive is off
•
Power for the fused protected terminals will be provided from the load side of any supplied contactor, circuit breaker, or disconnect switch.
24 VDC Power Supply
•
5 amp, 120 W, 24 VDC
•
Protected against output over-current, overload, short circuits, and over-temperature
•
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
Designed for monitoring temperatures of external system components, such as the motor windings and/or bearings. Includes eight universal input modules
plus two dedicated thermistor input modules. All ten modules are integrated into the drive's safe-stop circuit and can be monitored via a fieldbus network
(requires the purchase of a separate module/bus coupler).
Universal inputs (8)
Signal types:
•
RTD inputs (including Pt100), 3-wire or 4-wire
•
Thermocouple
•
Analog current or analog voltage
Additional features:
•
One universal output, configurable for analog voltage or analog current
•
Two output relays (N.O.)
•
Dual-line LC display and LED diagnostics
•
Sensor lead wire break, short-circuit, and incorrect polarity detection
•
Interface setup software
Dedicated thermistor inputs (2)
Features:
•
Each module capable of monitoring up to six thermistors in series
•
Fault diagnostics for wire breakage or short-circuits of sensor leads
•
ATEX/UL/CSA certification
•
A third thermistor input can be provided by the PTC Thermistor Option Card MCB 112, if necessary
