Precision Zone Expertly Repairs Inverter-Crane Magnetek P3 Series 1
Here at Precision Zone, one of our specialties is the repair services of Magnetek inverter units. One series that we often work on is the Impulse P3 S1 series.
The Impulse series of electromotive inverters is designed for high performance in crane, hoist and monorail applications. Easy adjustment of parameters and monitoring of drive display can be done directly on the drive using the digital keypad. The Impulse P3 S1 inverter line uses high performance pulse width modulation to more closely emulate sinusoidal output current. This allows for variable speed control of the conventional 3-phase induction motors. What sets the Impulse series apart from other standard inverters is the special application hardware and software combination. The unique configuration is designed exclusively for crane, hoist and monorail use, making the Impulse series the inverter of choice in these applications.
When assessing the functionality of a Magnetek Inverter, our expert repair team of engineers and technicians conducts a four-step check:
- 1. Visual Overview
- 2. Static Test
- 3. Checks Under Power
- 4. Alarm Codes Verification
This overview is Precision Zone’s basic troubleshooting process. Once our repair team starts on the job, we use specialized and customized testing fixtures, Huntron trackers, signal generators, oscilloscopes, milli and megaohm meters, as well as any other necessary tools we have available to assure quality repair work. Most importantly, every repair is fully tested in our custom-built simulators under load with a motor to replicate real-life working environment.
Precision Zone goes as far as using heating chambers and overnight dynamic testing, when applicable, to guarantee performance of the repaired product when it arrives back with the customer.
Repair Process for Magnetek Impulse Inverter Drives
Visual Overview
When conducting a visual check, the technician inspects the drive for any mechanical damage to the drive itself and any printed circuit boards (PCB). The technician then proceeds to verify connections are tight and correct inside the drive and there are no loose screws, wires or debris. Additionally, the unit is checked for any burn marks on the components, PCBs or chassis. During the visual inspection, excessive dirt on cooling components is noted as well as the functionality of the heat sink.
Basic Static Check
Input Module Testing
The input modules on these units can be tested by use of a digital multimeter with diode checking capabilities. Upon removing the cover, all of these terminals can be located along the terminal strip found within the unit.
Positive Lead | Negative Lead | Reading |
---|---|---|
L1 (R) | 'P' or + Terminal | 0.40V-0.64V |
L2 (S) | 'P' or + Terminal | 0.40V-0.64V |
L3 (T) | 'P' or + Terminal | 0.40V-0.64V |
'N' or - Terminal | L1 (R) | 0.40V-0.64V |
'N' or - Terminal | L2 (S) | 0.40V-0.64V |
'N' or - Terminal | L3 (T) | 0.40V-0.64V |
Output Module Testing
Using the same type of test as above, the output modules can be checked as well. Our technicians are also equipped with huntron devices further verify their integrity.
Positive Lead | Negative Lead | Reading |
---|---|---|
U (T1) | 'P' or + Terminal | 0.40V-0.48V |
V (T2) | 'P' or + Terminal | 0.40V-0.48V |
W (T3) | 'P' or + Terminal | 0.40V-0.48V |
'N' or - Terminal | U | 0.40V-0.48V |
'N' or - Terminal | V | 0.40V-0.48V |
'N' or - Terminal | W | 0.40V-0.48V |
