8.  Cleaning

The 

MEGAMAT 4 

drive system has been designed to facilitate cleaning for the user, and this 

has been made even easier thanks to the large number of flat surfaces.
The 

MEGAMAT 4 

drive system should be cleaned with a household cleaning agent suitable 

for plastic using a damp cloth. Always note the instructions provided by the manufacturer of 
the respective cleaning agent used.  

Before cleaning, always pull out the mains plug of the controls!

Never clean the drive system in a wash tunnel or with a 

high-pressure cleaner nor spray 

liquids onto it

. You otherwise risk damaging the equipment!

When 

cleaning

 take care not to damage the drive system’s 

connection lead

!

In its basic version the drive system meets the requirements of the IP20 protection category. 
You have the option of upgrading the protection category up to IPX4.

Do not use any solvents

 such as 

benzene

alcohol

 or similar substances. 

9.  Disposal

The 

MEGAMAT 4

 drive consists of electronic components, cables and metal and plastic 

parts. You should observe all corresponding national and regional environmental regulations 
when disposing of the 

MEGAMAT

 4 drive.

The disposal of the product is regulated in Germany by Elektro-G, internationally by the EU 
Directive 2012/19/EC (WEEE), or by any applicable national laws and regulations

The 

MEGAMAT 4

 drive system may not be disposed of with the 

normal household waste!

aintenance and Repairs

Problem

Possible Cause

Remedy

Handset or drive 
system without 
function

Drives suddenly no 
longer respond, no 
movement takes 
place

- Thermoswitch on transformer or in    
   the 

 controls has possibly

DewertOkin

  been triggered
- Temperature fuse in transformer 
  has possibly been triggered 
- Instrument fuse has possibly been    
  Triggered
- No supply voltage
- Lead (mains   and/or handset/slave 
  drives) interrupted

- Handset or drive system defective
- No supply voltage

- Contact your supplier/dealer
- Connect to mains

- Leave the drive system in 
  the rest position for approx. 
  20-30 minutes

- Contact your supplier/dealer

- Connect mains cable
- Check the lead, if necessary

  restoring contact

Actuator installation 
not possible or the 
actuator generates a 
click sound at the 
lower limit switch if it 
is retracted in the 
application.

- The fitting dimension from the 

application doesn't match with the 
corresponding actuator.

- Measure the mounting points 

in the application (e.g. with a 
distance gauge) and rework 
the mounting points if 
necessary.

After some cycles, the 
actuator or the GQR 
function is faulty.

- The mechanical stops in the application 

do not exist, or are not in line with the 
fitting dimension of the actuator.

- Check the fitting dimension of 

the actuator matched to the 
fitting dimension of the 
application. Rework the 
mounting points if necessary.

The clutch 
disengagement is 
rough-running. 

- The actuator fixing in the mounting 

points is too tight.

Please check:
- Screws and Screws size 
- Clevis size and width size 

 

-  Misalignment of latches
- Rework the mounting points if 

necessary.

Motor is running but 
the actuator does not 
move or the actuator 
is retracted by itself.

- The freewheel function has been 

permanently / daily used to adjust the 
application.

- Replace the actuator.  

 

(The internal freewheel 
function is destroyed, it is a 
protection function and not 
suitable for the adjustment.) 

Problem

Possible Cause

Remedy

Motor is running, the 
actuator does not 
move, the actuator is 
retracted by itself. Not 
or rough-running 
release function is 
given. 

- Actuator overloads by e.g. a collision 

with an obstacle.

- Check the free travel of the 

application. Replace the 
actuator on suspicion of a 
damage. 

Motor is running but 
the drive does not 
move

- GQR Bowden cable is not at the        

starting position, too much pre-
stressing on the Bowden cable.

- adjust Bowden cable
