Comprehensive reference for GEZE Slimdrive systems SL 1.7 to SL 1.9 and SL DCU 1.
Fault Codes – SL 1.7 to SL 1.9
Understanding Fault Messages
If a fault occurs on the system, a 2-digit number will be displayed on the program switch. This will flash every 20 seconds. Up to 5 separate fault codes may be issued in succession.
Audible Warning: If the system has been appropriately configured, an audible warning also occurs.
Support: To assist in fault diagnosis, please advise any fault codes to our office without delay when reporting the fault to the Service Dept.

Power Failure Procedures
Battery Operation
The presence of a battery determines whether the door opens or closes when the power fails. In most cases, the door will open in the event of power failure unless in Night mode (ni).
If Battery is Present:
- If the door is to be locked from the outside, operate the outside key switch (>4 seconds) until the programme switch lights up.
- Select "ni" (Night) by pressing the half moon symbol once: the door opens, closes, and locks once.
- If the battery is discharged, refer to the "No battery present" section below.
No Battery Present or Battery Discharged:
- Open: Unlock door manually and open door leaf by hand.
- Close: Close the door leaf by hand and manually lock the door.
After Power Restoration
- Door automatically returns to the previously selected operating state.
- OR: If the door is locked, it automatically changes to "Night" mode.
Fire Alarm Activation (if fitted)
- Automatic Setting: Doors will power open and remain in the fully open position until the fire alarm has been reset.
- Night Position: Doors will remain closed/locked so as not to compromise security.
Service Indicator
When the service indicator LED is lit, an annual service is required.
General Cleaning & Maintenance
Maintenance of Drive Unit
Aluminium Cover
Wipe clean with a damp cloth. DO NOT allow water to enter through the drive unit cover.
Activation & Safety Sensors
Ensure plastic lenses are clean & dust free. Wipe with a dry soft cloth if necessary.
Material Care
Atmospheric deposits, sulphurous acids, carbon dioxides, and other chemicals in the air will discolour and tarnish all metalwork, and in time cause corrosion. Regular maintenance prevents atmospheric deposits building up.
Anodized Aluminium
- Cleaning: Wash with mild soap and water or a mild detergent solution, rinse down with clean water and dry off with a soft cloth or chamois leather.
- Protection: Apply a liquid wax polish to protect the metal from the atmosphere.
- AVOID: Metal polish of any kind, abrasive cleaners, strong alkalines or acids, and ammonia-based cleaners.
- Frequency: Weekly.
Polyester Powder Coated Aluminium
- Cleaning: Wash at intervals of not more than three months using a solution of warm water and mild detergent (e.g. 5% Teepol solution or mild washing up liquid).
- Tools: Use a soft cloth or sponge. Nothing harsher than a natural bristle brush.
- AVOID: Abrasive cleaners or cleaning solutions such as ketones, esters, or alcohols.
- Frequency: Every 3 months (depending on environment).
Polished or Satin Stainless Steel
- Cleaning: Wash away grime and grit with luke warm soapy water or a mild detergent solution using a nailbrush for awkward crevices. Repeat with clean water.
- Result: Dry and polish with a soft duster or chamois leather.
- AVOID: Metal polishes, all abrasives, toxic materials, acids, strong alkalines, nylon pads, wire wool.
- Frequency: Weekly.
Glass
- Cleaning: Wash as often as possible with clean water and a chamois leather, scrim or squeegee, and dry off.
- Tip: The occasional application of a proprietary window cleaner or polish can be beneficial providing it does not contain ammonia.
