Lenze E82ZP PTC-MODUL 00454243 – Thermistor Evaluation Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82ZP PTC-MODUL (part number 00454243) is a specialized motor thermal protection evaluation module engineered for the Lenze 8200 vector frequency inverter series. Operating as a plug-in function module, the E82ZP provides direct monitoring of motor winding PTC thermistors built to DIN 44081 and DIN 44082 standards. It installs directly into the front function interface slot of the host drive, drawing internal control power to ensure continuous thermal supervision of industrial AC induction motor windings across applications in machine building, material handling, packaging, and plastics manufacturing.
Connecting the module into an existing drive architecture is achieved via the front function interface slot and dedicated terminals labeled T1 and T2 for sensor wiring. Commissioning a replacement E82ZP requires zero software programming or parameter transfer because the 8200 vector host inverter performs automatic hardware recognition upon powering up. To restore operational readiness, technicians simply isolate power, swap the hardware module in the front slot, and reconnect the thermistor wiring. ABC Industrial Parts supports maintenance teams seeking tested replacement units to maintain legacy drive panels without modifying machine control logic.
Thermal supervision operates through active resistance evaluation across terminals T1 and T2. When motor winding temperatures cause thermistor resistance to rise above 3.6 kOhm or if terminal wiring breaks, the module triggers an OH4 motor overtemperature trip on the host inverter, stopping drive output to prevent severe winding damage. Integrated line supervision also detects wiring short circuits below 20 Ohms. Drive status and fault conditions can be reviewed on the Lenze E82ZBC operating module keypad or through Lenze Global Drive Control engineering software. Basic troubleshooting involves verifying motor cooling, inspecting T1 and T2 connections, and verifying cold motor thermistor resistance between 50 and 1500 Ohms prior to resetting the trip after the resistance falls below 1.65 kOhm.

Programming and Configuration
The Lenze E82ZP PTC-MODUL operates without requiring manual software programming or parameter transfer. The host Lenze 8200 vector frequency inverter automatically detects the module upon insertion into the front function interface slot, integrating the hardware protection functions into the drive's operating logic without user intervention.
System diagnostic evaluation and fault monitoring can be accessed through standard Lenze engineering tools. Operating status and trip indications are visible using the Lenze E82ZBC Keypad Operating Module or by connecting through Lenze Global Drive Control (GDC) engineering software.
Diagnostics and Status Indication
Diagnostic readout for the E82ZP module is managed directly through the host 8200 vector inverter interface. When sensor loop resistance exceeds 3.6 kOhm or an open circuit is detected across terminals T1 and T2, the drive registers and displays error code OH4, interrupting inverter output to protect the motor.
Technicians can review active trips and monitor system conditions using the Lenze E82ZBC operating keypad or Lenze Global Drive Control (GDC) software. Line monitoring within the module also provides protection against shorted field wiring by initiating a trip if sensor resistance drops below 20 Ohms.
Replacement and Spare Part Considerations
Replacing a damaged or failing E82ZP thermistor module is a direct hardware swap. Because the host Lenze 8200 vector frequency inverter automatically recognizes the module, no parameter configuration, firmware alignment, or project download is necessary when putting a spare unit into service.
During replacement, standard safety practices must be followed by completely de-energizing the inverter system before removing the module from the front function interface slot. ABC Industrial Parts offers fully tested replacement units to restore thermal protection capabilities in legacy machine control installations.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OH4 | Motor temperature trip (PTC thermistor) | PTC thermistor evaluation module E82ZP detected excessive resistance (> 3.6 kOhm) or open circuit across terminals T1 and T2. | Motor thermal overload; inadequate motor cooling/fan failure; ambient temperature too high; broken wire in PTC thermistor connection; damaged PTC sensor. | Allow motor to cool down. Check motor load and ventilation. Measure PTC resistance across wires (should be 50 to 1500 Ohm at cold motor temperature). Inspect terminal wiring on T1 and T2. |
Frequently Asked Questions
What is the function of the Lenze E82ZP PTC-MODUL?
The Lenze E82ZP (part number 00454243) is a plug-in thermal protection module for Lenze 8200 vector frequency inverters. It continuously monitors motor winding PTC thermistors meeting DIN 44081 and DIN 44082 standards to protect against overtemperature conditions.
How does the E82ZP module signal a fault to the host inverter?
When motor thermistor resistance exceeds 3.6 kOhm, or if an open circuit or short circuit below 20 Ohms occurs, the module triggers an OH4 motor overtemperature trip on the host drive to halt output.
Is software programming required when installing a replacement E82ZP module?
No software programming or parameter transfer is required. The host Lenze 8200 vector inverter automatically recognizes the hardware module when inserted into the front function interface slot.
How do I troubleshoot an OH4 fault code on the Lenze 8200 vector drive?
Verify motor cooling and ambient temperature, check terminal connections T1 and T2, and measure sensor resistance across the wires. Resistance should measure between 50 and 1500 Ohms when the motor is cold.
What engineering tools can be used to view diagnostic information for the E82ZP?
Diagnostic status and fault readouts can be viewed using the Lenze E82ZBC keypad module or Lenze Global Drive Control (GDC) engineering software.
