Issue:
Why is the display blank on the trip unit?

Product Line:
Powerpact P frame, Powerpact R Frame, Masterpact NT, Masterpact NW

Resolution:
The LCD display on a Micrologic P or H trip unit will be blank unless the trip unit is energized.  Energization requires one of the following sets of conditions:

1. The trip unit is energized by an external 24 Vdc applied to terminals F1-F2 (F1 negative-F2 positive)
2. The trip unit is energized by an FFTK or HHTK test kit
3. There is at least 100 V between two phases, AND the load reaches approximately 20% of the breaker's rated current.

• Note that the display will not power up with primary injection testing unless one of the conditions in bullet 1 above is met.
• Note that Ammeter trip units do not require external power and the display will come on with sufficient current flow alone.

See the following bulletins for more information on these trip units.
 

The drive is in 2 wire control (TCC = 2C) and was powered up with an active run command.
Cycle the run command or set TCT to LEL. (IO menu, 2 wire type = level)
https://www.se.com/ww/en/faqs/FA238669/

The drive has an input assigned to Freewheel stop, NST.
The input needs to be active.
https://www.se.com/ww/en/faqs/FA170907/

The drive is in 3 wire control (TCC =3C).
LI1 must be active before the NST will clear.
https://www.se.com/us/en/faqs/FA274804/

The drive is being controlled by serial communication, and drive is not receiving the proper command signal.
The drive will display NST until the correct value has been written to the command word.
https://www.se.com/ww/en/faqs/FA314997/

A loss of a 4-20mA signal is programmed to freewheel stop.
When the input is lost, status goes to NST. Verify the 4-20 mA signal.

The drive is in terminal control, and the STOP button on the integral or remote keypad was pressed.
While in terminal control, the STOP button functions as an E-STOP.  If the keypad STOP button is pressed, the drive will go to NST (excluding the ATV212, which will display a flashing "E"). Power cycle the drive to clear the NST.

For the ATV61/71 VFD only: If the drive is running, and the voltage applied to the PWR input terminal drops below +19Vdc, the drive will stop and display NST.
You will need to make sure you close the +24 VDC to PWR input and cycle off and on the run command again. Make sure the factory-installed jumper between +24 and PWR is connected firmly. Or if a safety circuit is connected to these terminals, be sure the circuit is closed.

The power limitations to the shutter relay L5501RBCP are a maximum load output of 24V DC, 24-240V AC and a maximum motor load of 2A.

Some of the key features for the L5501RBCP are:

• DIN rail mounted, 2M wide
• AC input impedance 80 kOhm at 1 kHz
• Electrical isolation 3.75 kV RMS from C-Bus to mains
• Maximum units per network 80
• Load current rating 2 A (motor load)
• Load voltage rating 24 V DC, 24 - 240 V AC
• Warm up time 5 s
• Network clock software selectable
• Network burden software selectable
• Class II switch
• 4 kV rated impulse withstand voltage
• 0 - 45 deg C operating temperature
• 10 - 95% RH operating humidity
• Mains terminals Accommodates 2 x 1.5 mmsq or 1 x 2.5 mmsq (2 x 15 AWG or 1 x 13 AWG)

 
 

If you are after a replacement electronic switch for a 5012S164/4L-WE then order the standard item “B5034MNLPCB-WE” which contains a PCB Assy plus the Rear Cover.

If you are after an equivalent to a 5012S164/4L-WE the closest we have can be achieved by ordering 1 x “B12/30/6-WE” + 3 x “5031NMML” + 9 x “5031NMS”

 

If just for replacement then you could get B503xNL and remove the Metal Plate and just use the gang switch to replace the old unit.

B5031NL, B5032NL, B5034NL


 

The DC operating voltage that can be applied to 4CB150/6 is - 48VDC
