Operational Description TST WS-B

Mounting of the control device
•
Before mounting, the control device is to be checked for damage which may have occurred during
transportation or for some other reason. Damage inside the control device can lead, under certain
circumstances, to considerable subsequent damage to the control device and even pose a health risk for the
user.
•
During mounting of the control device, the installation is to be made voltage-free.
•
The control device is provided for mounting directly on a wall. It is attached by means of the wall-mounting
device located on the underside. The control device must always be mounted in such a way that the cable
lead-ins always point downwards. It is to be ensured that no transfer of mechanical vibrations through the
door to the control device is possible (eg mounting on a masonry wall).
•
Mounting must only be to flat surfaces. The housing must be mounted in a distortion-free manner.
•
The mounting site is to be selected such that the control device is not subjected to direct sunlight and so that
the weather can not otherwise have any direct effect on the control device.
•
The door to be operated must be visible from the control device in order to permit deadman operation which is
possible from the membrane keypad.
•
The touching of electronic parts, in particular, the parts of the processor circuit is to be avoided. Electronic
components can be damaged or destroyed by electrostatic discharge. It if is not possible to avoid touching of
the electronic components, an earthed location must be contacted shortly before (eg an earthed door frame).

Electrical connection
•
Connection, checking and maintenance work on the opened control device must be carried out only in the
voltage-free state. Particular attention should be paid to the points set out in the Safety instructions section.
•
The control device is only designed for a nominal voltage of 230/400 V±10% 50/60 Hz. Neutral and protective
earth conductors must be connected. In operation at 230V the clamping sites L3 (contactor), N and PE must
be used.
•
The supply inlet is to be secured at the installation site with 16A actuation feature K. The drives are to
be fitted with additional over-load protection (eg thermoplate).
•
If the voltage free contacts of the relay outputs or other terminal clamps are connected to a external supply,
that means they have a dangerous voltage which can be active after switch off of the control ore disconnecting
of the supply plug, a warning sticker has to be mounted visible on the control box: "NOTE! Before working on
terminal clamps, all power circuits must be switched off."
•
The control voltage 24V
are to be secured by a self-resetting semi-conductor protection device. Resetting takes place after the
overload or short-circuit has been overcome and after a short cooling phase.
•
All control voltage inputs are dc-insulated from the supply by a basic insulation. They are arranged irregularly
for 24V
, wherein the inputs can be provided with potential-free contacts or limited with 24V active outputs.
DC
•
According to EN60335 all components connected to the control device must have also basic insulation for a
operation voltage up to 230V
•
Extremely high electrostatic charges can occur in doors. Discharging takes place via the closest point which
has a protective earth conductor covering. If, by reason of incorrect cabling, discharge onto the control inputs
which are under the earth covering is made possible, the control device may be damaged. The connections of
the security strip are particularly at risk. As a countermeasure, a discharge device on the door leaf is to be
recommended.
•
The connection for the cables introduced into the control device is to be kept as short as possible and to lead
as directly as possible to the connection clamp.
•
Maximum connection cross-section of the used terminal clamps:
single wire (rigid)
thin wired /with/without vein end
sleeve
•
Connection arrangement see separate drawings in appendix.
Under no circumstances leave behind mounting or wiring remains in the control
housing. Electrically conductive remains can lead to severe damage on the printed
Tighten all screws on the contactor, even those assumed not to be used.
