Options and Accessories
Safe Stop with Pilz Relay
Provides a solution for the "Emergency Stop" option
without the contactor in F-Frame frequency converters.
Manual motor starters
Provides 3-phase power for electric blowers that are 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 frequency converter is off. If a 30 A fuse-protected
circuit is ordered, only one starter is allowed, otherwise 2
starters may be selected. The starter is integrated into the
Safe Torque Off 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
•
9 9 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
contactor, circuit breaker, or disconnect switch.
24 V DC power supply
•
5 A, 120 W, 24 V 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
Monitors temperatures of external system components
such as the motor windings and/or bearings. This option
includes 5 universal input modules. The modules are
integrated into the Safe Torque Off circuit and can be
monitored via a fieldbus network. This requires the
purchase of the Safe Torque Off option and separate
module/bus couplers.
Universal Inputs (5)
Signal types:
•
RTD inputs (including PT100), 3-wire or 4-wire
•
Thermocouple
