2.4 General safety information
The following general safety instructions must always be observed:
- Mounting, maintenance, servicing and inspection may only be carried out by designated and trained specialist personnel.
- Read these instructions carefully before any mounting work.
- These instructions must be kept for later use.
- Observe the warnings in the individual chapters and before the instructions for action.
- The ambient temperatures specified in the technical data must be observed.
- At very high ambient temperatures or on facade or roof structures exposed to direct sunlight, the drives may heat up to such an extent that there is a risk of burns if touched.
Product description
The chain drive KCDL is a quiet, modular chain drive for opening and closing bottom-hung, top-hung, side-hung and roof windows. The chain drive is suitable for smoke/heat extraction and natural ventilation.
3.1 Special features
Simple sash or frame mounting with brackets that allow an opening angle of up to 50° for inward-opening bottom-hung windows and up to 80° for outward-opening top-hung windows.
The factory settings can be easily changed without the need for a PC tool. Configuration options are:
- Limit the opening width
- Search for zero position (closing position) again
- Plug-on function modules:
- 24 V DC ventilation
- 24 V DC SHE
Force 600 N in tension and compression (see Force-Distance diagram page 51)
OPEN and CLOSE indication, potential-free contacts integrated in the SHE function module Seal closure relief, adjustable
Automatic reversal in the “closing” direction (CLOSED) in case of overload
3.2 Transport and storage
The chain drive must only be transported and stored in its original packaging. It must not be knocked, dropped or
exposed to moisture, aggressive vapours or harmful environments.

Manual configuration/commissioning
CAUTION
Danger of crushing body parts
Body parts can be crushed when closing the window.
When opening and closing the window, make sure that there are no persons near the window.
NOTICE
The drives are configured as individual drives at the factory. Manual configuration is necessary (to connect / synchronise several drives) and is only possible on the DC ventilation function module.
The following configurations can be set using it:
- Connecting and synchronising chain and dead bolt drives with each other
- Teaching the zero position (= sash closed)
- Limiting the opening width
- Setting the pinch protection range
NOTICE
The opening width in SHE mode is basically the same as the opening width configured for ventilation mode.
8.1 Connecting and searching for zero position
- If there are several drives on one sash: Connect the drives electrically to each other using the interconnection.
- Connect the connecting cable to the DC ventilation function module of the drive. Configuration via the SHE module is NOT possible.
- Connect the power supply (24 V DC with pole reversal function) of the connecting cable (white and brown wire).
The following illustration shows the connection of the jumper wire for configuring the drives.
| Structure chart/configuration sequence | Step | Sequence of actions |
 |
Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 |
►Apply voltage in the OPEN direction (for example, an OPEN command via a ventilation button). ▷ The drives start to extend the chain. ► Connect the green wire (communication A) and the white wire (24 V) of the connecting cable with a jumper wire for approx. 1 second. ▷ The drives stop for 6 to 9 seconds (the drive set is formed). ►Then move slowly in the CLOSED direction until the sash is closed. ▷ This position is saved as the zero position. ►Then move slowly in the OPEN direction. ATTENTION :If NO opening width limitation is desired, the chain must be extended to the maximum. Limiting the opening width ► When the desired opening width is reached, interrupt the voltage (e.g. by a STOP command via a ventilation button). ► Apply voltage in the CLOSED direction (e.g. by a CLOSED command via a ventilation button). ▷ The drives save the achieved opening width and slowly move in the CLOSED direction. If no pinch protection range is to be defined, steps 8 and 9 are omitted. ► Allow the drive set to close completely. Setting the pinch protection range ► From the chain position at which the drives are to slow down their approach, apply a voltage in the OPEN direction (e.g. by an OPEN command via a ventilation button). ▷ The drives stop and remember this position as the start position for the decelerated pproach. ►Apply voltage in the CLOSED direction (e.g. by a CLOSED command via a ventilation button). ▷ The drives move slowly in the CLOSED direction until the sash is closed (zero position). ▷ The configuration is completed when the CLOSED position is reached. |

Fault
If a safe operation is no longer possible, take the chain drive out of operation.
Safe operation may not be possible under the following circumstances:
- The chain drive is damaged.
- The chain drive no longer functions.
- The chain drive has been stored under unfavourable conditions for a longer period of time.
Fault Cause Measure The window does not open or close. No power supply available. Chain drive defective. Check the power supply of the chain drive.
Check the line lengths and cross-sections
Check that the chain drive is connected correctly.
Maintenance/cleaning
HAZARD
Fatal injury hazard due to electric shock
Touching live parts may result in a fatal electric shock.
- Before starting maintenance work, switch off the power supply and secure it against being switched on.
CAUTION
Danger of crushing body parts
Body parts can be crushed when closing the window.
When opening and closing the window, make sure that there are no persons near the window.
CAUTION
Burn hazard due to hot surfaces
At very high ambient temperatures or on facade or roof structures exposed to direct sunlight, the drives may heat up to such an extent that there is a risk of burns if touched.
- Always wear safety gloves when working near hot parts.
- Before maintenance work, let the chain drive cool down to the ambient temperature.
NOTICE
Maintenance work is only allowed to be done by skilled personnel.
- Visual inspection for damage
- Check the mechanical fastenings of the chain drive (check screws for tightness).
- Check the chain drive for damage and dirt
Clean the chain drive with a soft, dry and lint-free cloth. In case of heavier soiling, clean with a cloth slightly moistened with lukewarm water. Do not use cleaners containing solvents, as this will damage the surface.
The chain itself must NOT be cleaned wet. - Check correct functioning of the chain drive
- Check guards for entrapment protection
