Options and Accessories
Safe Stop + Pilz Relay
Provides a solution for the "Emergency Stop" option
without the contactor in F-Frame drives.
Manual Motor Starters
Provides 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
10 10
•
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, 120W, 24V DC
•
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 five universal input modules. The 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 (5)
Signal types:
•
RTD inputs (including PT100), 3-wire or 4-wire
•
Thermocouple
•
Analog current or analog voltage
