White Electric | Automatic Twin Socket Outlet, 250VAC, 10A, 1 Pole

Issue:
PID setup for the ATV61 or ATV71 drives.

Product line:
ATV61 and ATV71

Environment:
All models, all serial numbers

Cause:
PID set up to maintain pressure control with a fixed pressure set point

Resolution:
1.7 Application function menu -> PID regulator

Issue:
What is the function and electrical characteristics of the auxiliary switch, alarm switch, and overcurrent trip switch for the PowerPact P, R, and NS630b - NS3200 electronic trip circuit breakers?

Product Line:
PowerPact and Masterpact breakers

Resolution:
AUXILIARY SWITCH (OF)
An auxiliary switch is a single pole, double throw switch operated by the movable contact arm assembly. It is used to remotely indicate the position of the main circuit breaker contacts, whether open or closed.

ALARM SWITCH (SD)
An alarm switch indicates that the circuit breaker has tripped due to an overload, short circuit, or ground fault, the operation of a shunt trip or undervoltage trip, or the push-to-trip button. The alarm switch resets when the circuit breaker is reset.

OVERCURRENT TRIP SWTCH (SDE)
An overcurrent trip switch indicates that the circuit breaker has tripped due to an overload, short circuit, or ground fault. The overcurrent trip switch resets when the circuit breaker is reset.

These switches are available in low level versions (with gold flash plating) capable of switching very low loads (e.g. for controlling PLCs or electronic circuits).
 

Issue:  
2 wire, 4-20mA transducer wiring.

Product line:
Altivar ATV61 and ATV71

Environment:
All models, all serial numbers 

Cause: 
A 2 wire transducer needs to be wired to the drive for a pressure feedback signal.  
 
Resolution:
Wire the 2 wire transducer as follows:
The input of the transducer typically requires 24Vdc.  This may be wired to the VFD terminal +24 or to an external power supply.
The output of the transducer is wired to the VFD terminal AI2.
Program the AI2 Configuration for 4-20mA.  See attached file.

Issue:
Altivar drives used in equipment that aren't motors.

Product Line:
All Altivar drives

Environment:
All models and serial numbers

Cause:
None

Resolution:
Altivar drives are designed for motors.  If an application calls for supplying power to anything other than a motor, a drive should not be used for that application.

Issue:
ATV312 Safe Torque Configuration

Product Line:
ATV312

Environment:
All serial numbers for ATV312

Cause:
N/A

Resolution:
No, the ATV312 does not have a Safe Torque Off option. That feature is only compatible with the ATV32, ATV320, ATV61, ATV71 , ATV630 and ATV940 drives

Issue:
nCr parameter on Altivar Drives

Product Line:
Altivar 

Environment:
ATV312, ATV61, ATV71, ATV32, ATV12

Cause:
Programming

Resolution:
nCr is the Rated motor current.
Its adjustment range goes from 0.25 to 1.5 In (1) and factory setting According to drive rating and [Standard mot. freq] (bFr).
Rated motor current can be found on the motor's nameplate.
