Installation
Safety Notices to Observe During Installation
Basic safety rules must be followed for safe operation and installation of the end product and the MCL III control unit.
Avoiding Electrical Faults
The connecting cable connects to the (PD15) power supply. Ensure the connecting cable is never squashed during operations.
Ensuring Operational Reliability During Installation
Safety and reliability are ensured by using proper construction methods.
Mechanical Construction
A plug cover protects connections from mechanical damage and minimizes the risk of accidental unplugging.
Installation Procedure
Before installing, ensure all safety notices from the "Safety notices to observe during installation" section are followed.
Installation and Dismounting for the Control Unit
The MCL III control unit has four mounting holes for attachment to the end product using appropriate screws (e.g., 4.5 mm x 30 mm screws: DIN 7981). Mount the unit flat against its supporting material. No mechanical forces (like torsion) should be applied to the unit or its housing, as this could cause cracks.
Figure 8: MCL III control unit mounting points (in mm). Shows dimensions 101.6, 76, and Ø 5.2.
Option: Installing the Strain Relief Cable Grip for the MCL III Control Unit on the End Product
The strain relief for the power cable is installed on the end product as shown in Figure 9.
Figure 9: Mounting the strain relief cable grip (an example application). Shows steps: 1. Unscrew hex nut (A). 2. Insert strain relief (B) through slot in end product (C). 3. Tighten hex nut (A).
Option: Route the Connecting Cable Through the MCL III Control Unit's Strain Relief Cable Grip
The method for routing the connecting cable through the cable grip is shown in Figure 10.
Figure 10: Routing the connecting cable through the mounted cable grip. Shows steps: 1. Take a loop of the connecting cable and guide it through the strain relief cable grip. 2. Pull the cable slightly forward. 3. Put the cap onto the cable grip; it must snap on properly.
Electrical Connection
⚠️ CAUTION: Electrical components should be connected or disconnected only when the power supply cord (connecting cable) is unplugged.
ℹ️ NOTICE: There is a delay after supply voltage is applied before the device turns on. Wait at least seven seconds before commissioning.
Routing the Electrical Cables
When routing cables, ensure:
- Cables cannot get jammed.
- No mechanical load (pulling, pushing, bending) is put on the cables.
- Cables are not damaged.
Fasten all cables using kink prevention methods. Ensure the end product design prevents connecting cables from contacting the floor during transport.

Operating Notes
This information may be used for creating the end-product manual. These installation instructions describe assembly and operation of the MCL III control unit as a partially assembled piece of machinery, not all information for safe end-product operation.
⚠️ CAUTION: Installation instructions are intended for qualified specialists, not typical end-product users.
General Information
Only DewertOkin's Megamat MCZ, MFZ, or MXS drives should be connected to the MCL III control unit.
Power-on Time / Intermittent Operations
The MCL III control unit is designed for intermittent operations. This mode requires the drive to pause after a maximum operation period (power-on time) to prevent overheating and malfunction. The ratings plate specifies the maximum power-on time and required pause intervals.
Avoiding Toggle Operations
Avoid switching directions without first stopping the motor. Pause between motions. A pause (motor stop time) can be activated using the controls.
ℹ️ NOTICE: Always avoid quick changes (toggling) of directions.
Avoiding Electrical Risks
⚠️ CAUTION: Ensure no live (current-carrying) parts of the drive system and power supply can be touched. Unused power and control unit connections must be adequately covered.
Emergency Shut Off of a Connected Drive or Control Unit
⚠️ CAUTION: Be sure to unplug the PD15 power supply from the power outlet before cleaning. This outlet must be accessible at all times. Alternatively, disconnect the plug on the MCL III control unit from the PD15 power supply. If an optional battery is connected, disconnect its plug from the MCL III control unit.
Avoiding Cable Damage
Ensure operating instructions inform users about possible cable risks.
⚠️ CAUTION: Cables (especially the connecting cable) should not be run over. To prevent injuries or damage, no mechanical strain should be placed on the cables.

Troubleshooting
This chapter describes troubleshooting methods for fixing problems. If an error is not listed, contact your supplier.
⚠️ CAUTION: Only qualified specialists who have received electrician training should carry out troubleshooting and repairs.
| Problem | Possible Cause | Solution |
|---|---|---|
| The drive or control unit is not functioning. | There is no mains supply voltage. | Connect the mains power. |
| The drive or control unit is defective. | Please contact your supplier or sales agent. | |
| The drive is suddenly not capable of movement. | The overheating protection or system protection has been triggered. | Remove the overload (change or remove the load). Allow the system to rest for 20 to 30 minutes with the mains power unplugged. If this does not resolve the problem, contact your supplier or distributor. |
| The unit's fuse may have been triggered. | Please contact your supplier or sales agent. | |
| There is no mains supply voltage. | Connect the mains power. | |
| A cable has been disconnected (to mains power, drive or control keypad). | Check the cables and reinsert them, if required. |
Maintenance
Only use spare parts manufactured or approved by DewertOkin for sufficient safety.
Maintenance
| Type of check | Explanation | Time interval |
|---|---|---|
| Check the function and safety of the electrical system. | A qualified electrician should carry out this inspection. (Refer to the "Electrical connection" section in the "Installation" Chapter.) | Periodic inspections can be carried out at intervals based on the risk assessment which you conduct for your end product. |
| Look over the housing periodically for any signs of damage. | Check the housing for breaks or cracks. | At least every six months. |
| Look over the plug-in connections and electrical access points for signs of damage. | Check that all electrical cables and connections are firmly seated and correctly positioned. | At least every six months. |
| Look over the cables for any signs of damage. | Check the connecting cables for pinching or shearing. Also check the strain relief and kink protection mechanisms, in particular after any mechanical load. | At least every six months. |
| Check periodically to see if the rechargeable battery is ready and operational. (Battery is optional) | If you can no longer move the drive in both directions with a fully charged battery, then you should replace the battery. | At least every four weeks. |
Cleaning and Care
