Frequently Asked Questions - VE 340 A Vemer
What is the Vemer VE 340 A used for?
It is a programmable time switch designed to control lighting circuits, such as indoor and outdoor lights, automatically according to weekly or astronomical schedules.
How do I install the VE 340 A?
Mount the unit on a standard 35 mm DIN rail in a distribution board. Connect the supply and load as shown in the manual. Work must be done by a qualified electrician with the power off.
Can the VE 340 A work without being connected?
No, the device needs 230 V AC to operate. The backup battery only preserves the clock and program memory during power interruptions, not for continuous operation.
How do I set the current time and programs?
Use the buttons on the front panel and navigate the LCD menu. The manual explains the sequence: set the time, date, and then program on/off times. The device can also calculate sunrise and sunset automatically.
What is the astronomical timer function?
The astronomical function automatically calculates sunset and sunrise times based on geographic settings. This lets the lighting turn on at dusk and off at dawn without daily reprogramming.
Is the VE 340 A suitable for LED lighting?
Yes, provided the total load does not exceed the switching capacity and the inrush current of the LED drivers is handled correctly. Use a contactor for larger or capacitive loads.
How do I temporarily switch the lighting on or off?
Use the manual override button on the front panel. This toggles the output until the next programmed switching action.
How long does the battery backup last and what happens when it is empty?
The lithium battery can last approximately 4-5 years. When depleted, the clock and memory may be lost after a power failure. The battery should be replaced only by an authorized service center.
What maintenance does the VE 340 A require?
Maintenance is limited to occasional cleaning with a dry soft cloth. Check all electrical connections periodically and keep the ventilation slots free from dust.
Can I install the VE 340 A outdoors?
No, the IP20 rating makes it suitable only for indoor, dry locations. For outdoor use, place it inside an IP-rated enclosure.
