Danfoss Metasys N2 Instruction Manual

STO + Pilz Relay
STO + Pilz Relay provides a solution for the "Emergency
Stop" option without the contactor in F enclosure
adjustable frequency drives.
Manual motor starters
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 start, and is o when the
incoming power to the adjustable frequency drive is o.
Up to two starters are allowed (one if a 30 A, fuse-
protected circuit is ordered). The motor starters are
integrated into the adjustable frequency drive’s safe-stop
circuit.
Unit features include:
•
Operation switch (on/o).
•
Short circuit and overload protection with test
function.
•
Manual reset function.
30 A, fuse-protected terminals
•
3-phase power matching incoming AC line
voltage for powering auxiliary customer
equipment.
•
Not available if two manual motor starters are
selected.
•
Terminals are
o when the incoming power to
the adjustable frequency drive is o.
•
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
ve universal
input modules. The modules are integrated into the
adjustable frequency drive’s safe-stop circuit and can be
monitored via a serial communication bus 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,
congurable 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.
