8.3 Normal operation
During normal mode, the sliding gate operator only works
according to the impulse sequence control (OPEN-STOP-
CLOSE-STOP). It does not matter whether an external button,
hand transmitter button or circuit board button T has been
actuated:
▶
To open and close fully, press the appropriate impulse
generator for channel1.
▶
To open and close partially, press the appropriate
impulse generator for channel2.
8.4 Behaviour during a power failure
To be able to open or close the sliding gate by hand during a
power failure, it must be disengaged from the operator.
ATTENTION!
Damage due to moisture
▶
Protect the control from moisture when you open the
operator housing.
1. Open the housing cover as shown in Figure3.1.
2. Release the operator by turning the locking mechanism.
If necessary, press the motor and toothed wheel down by
hand (see Figure14.1).
8.5 Behaviour following a power failure
Once the power supply has been restored, the gate must be
reengaged with the operator upstream from the limit switch.
▶
Slightly lift the motor while locking it (see Figure14.2).
9 Inspection and Maintenance
The sliding gate operator is maintenance-free.
In the interest of your own safety, we recommend having the
gate system inspected and maintained by a qualified person
in accordance with the manufacturer's specifications.
WARNING
Danger of injury due to unexpected gate travel
Unexpected gate travel can result during inspection and
maintenance work if the gate system is inadvertently
actuated by other persons.
▶
Disconnect the mains plug and, if applicable, the plug
of the emergency battery when performing all work on
the gate system.
▶
Safeguard the gate system against being switched on
again without authorisation.
Inspection and repairs may only be carried out by a qualified
person. Contact your supplier for this purpose.
A visual inspection may be carried out by the operator.
▶
Check all safety and protective functions monthly.
▶
Check the function of the resistance contact strips8k2
every six months.
▶
Malfunctions and / or defects at hand must be rectified
immediately.
10 Displays for Operating Conditions,
Errors and Warnings
▶
See LED GN and LED RT in Figure6
10.1 LED GN
The green LED indicates the operating condition of the control:
Steady illumination
Normal state, all end-of-travel positions and forces
taught-in.
Fast flashing
Force learning runs must be performed.
Slow flashing
Set-up mode – end-of-travel position setting
When setting the reversal limits
Flashing frequency is proportional to the selected reversal
limit
• Minimum reversal limit: The green LED flashes 1x
• Maximum reversal limit: The green LED flashes 10x
When setting the hold-open phase
Flashing frequency depends on the set time
• Minimum hold-open phase: LED flashes 1x
• Maximum hold-open phase: LED flashes 5x
10.2 LED RT
The red LED indicates:
In set-up mode
• Limit switch actuated = LED is off
• Limit switch not actuated = LED is on
Display of the button inputs, radio
• Actuated = LED is on
• Not actuated = LED is off
In normal mode
Flashing code as an error / diagnosis display
10.3 Display of error and warning messages
The red LED RT helps to easily identify causes when
operation does not go according to plan.
NOTE:
If normal operation of the sliding gate operator with the circuit
board button T is otherwise possible, a short circuit in the
external button's connecting lead or in the button itself can be
recognised through the behaviour described here.
Display flashes 2×

20and73 missing
• Without SE3, wire jumper between terminals 20 and 71
missing
Remedy
• Check safety / protective device
• Check whether the appropriate resistance / wire
jumpers are present without the connected
safety / protective device
