Assembly and Operating Instructions
GU-SECURY Automatic with A-opener
7 Inspection and maintenance works, replacement parts
SECURY Automatic with A-opener must only be operated with power supply units meeting the
minimum requirements of the lock (see "Technical data" under 4.1)
Any warranty claims for damage caused by non-observance are rejected.
The serviceability of the locking system must be verified at regular intervals. For doing so,
check all fixing points and retighten screws, if required.
In order to avoid that the mechanical properties of the lock – especially with regard to key, han-
dle, and latchbolt movement – are affected by dirt, it is necessary that the lock is inspected and
lubricated with non-resinous oil at least once a year.
The A-opener itself is maintenance-free.
8 Trouble shooting / Possible causes / Remedies
Motor not running
Cable(s) connected wrongly or not at all, verify connections:
•
Voltage supply V direct voltage/alternating voltage
brown: +/~
grey (blue): -/~
black:
+/~ (control voltage for release).
•
Check transformer and exchange microfuse, if necessary.
•
Check terminals.
Latchbolts are retracted after activation, however not extended again.
Cable connected wrongly, verify connections:
•
Voltage supply V direct voltage/alternating voltage
brown: +/~
grey (blue): -/~
black:
+/~ (control voltage for release).
•
Milled recess for A-opener too small: driving rod gets jammed or stuck.
The recess must be cut larger.
Motor hums over a longer period of time or
A-opener cannot retract the latchbolts
A-opener not getting enough current, transformer too weak:
•
Check transformer:
Voltage supply V direct voltage/alternating voltage min. 1 Ampere (1000mA!)
Cables used are too long or too thin: verify cable cross sections:
- up to 10 m – 0.5 mm²
- up to 40 m – 0.75 mm²
- up to 50 m – 1.0 mm²
- up to 75 m – 1.5 mm²
- up to 125 m – 2.5 mm²
Consumers switched in parallel:
•
Transformer not powerful enough to provide the energy required for A-opener plus
additional consumers connected to it!
