When using components or modules it is necessary to strictly observe the specification given in the
corresponding description of these components.
•
If a description for a private end-customer not clearly states which electric data is valid for a component or a
module, how to wire the device, which external components or additional devices can be connected or which
parameters these components are allowed to have, a specialist must be contacted.
•
Before putting a device into operation, it has to be clarified, whether this device or module is meant for the field
of application. In case of doubt ask specialists or the manufacturer of the device.
•
Please note that we are not responsible for any errors in usage or connection. Therefore we cannot accept any
responsibility for consequential loss.
•
Devices which operate with >35 Volt have to be connected by a specialist.
•
Before putting the device into operation it should be checked that there is no current leakage on the housing.
•
In case that measurements with the opened housing are necessary, an isolating-transformer has to be
integrated for saftey reasons. Alternatively the voltage can be supplied by an appropriate power supply which
complies with the safety regulations. All wiring work has to be done in a voltage free state only.
Operating conditions
•
Operate the STD35 only with a supply voltage between 5-32V and have in mind the polarity! (see picture1) The
power supply has to deliver at least 500mA. If you use a mains adapter for power supply it has to be conform
with the VDE regulations.
•
Devices with an operating voltage >35 Volt have to be installed by a specialist observing the VDE regulations.
•
Loads connected to the device are not allowed to exceed 1000W per relay.
•
The maximum voltage is 250V AC (alternating current)
•
The maximum switching power per relay is 6A (depending on the width of the PCB tracks)
•
No special operation position of the device has to be observed.
•
When installing the device make sure that the supply cable has a sufficient diameter
•
During operation the temperature has to be between -20° and 55° Celsius.
•
In case of condensation allow a period of about 2 hours for acclimatisation.
•
Keep away the device from flower vases, bath tubs, washbasins, liquids etc.
•
The device is meant for operation in dry and clean rooms.
•
Protect the device from humidity, spray water and heat.
•
Do not expose the device to heavy vibrations.
•
Do not operate the device in areas where are or could be inflammable gas, vapours or dust.
•
The unit may only be repaired by a specialist.
•
Only original parts have to be used when repairing the unit. The use of differing spare parts can cause serious
material loss or personal injury.
Proper Use
The device is designed for the remote switching of devices via the GSM network as well as the remote retrieval of
status information of the inputs and the generation of SMS messages after status has changed at the inputs. A
different utilisation of the device other than the one described above is not allowed.
Introduction
The STD35 is a telemetry module which is easy to install and simple to use.
With the STD35 you can control five relays and monitor the status of five digital inputs with one or several common
mobile phones.
Apart from the STD35 you only need a valid SIM Card of any network provider (GSM 900 / 1800 MHz).
While using prepaid SIM-cards one shall always keep himself aware of the amount left on the card, so that in case
of alarms a SMS could be sent.
Typical fields of application are the opening of (garage) doors, switching on and off light and alarm devices as well
as generating alarm messages (SMS) or the retrieval of information from door sensors, movement sensors or level
sensors etc.
