Fan Unit ELS-V..
Installation and Operating Instructions
6.5 Operation
m
The safety instructions specified in section 1.2 must be observed!
In order to ensure the faultless functioning of the fan, the following must be checked regularly:
– Formation of dust or dirt deposits in the casing or on the motor and impeller
– Free movement of the impeller
– Occurrence of excessive vibrations and noises
In case of problems with one of the aforementioned points, maintenance must be carried out according to the instructions in
chapter 8.
7.0 Functional description Fan unit ELS-V..
Ventilation through activation/deactivation e.g. in combination with light switch or multistage with stage switch.
7.1 Functional description Fan unit ELS-VN.. overrun timer
Integrated overrun timer with set start-up delay of approx. 45 sec. and three specifically defined overrun times of 6,
15 and 21 minutes*, divided into 3 sectors on a dial. The times can be adjusted by setting the arrow to the respective
sector marking I, II or III (see Fig. 20). A flat-headed screwdriver with max. 2 mm width is required for this purpose.
The adjustment must take place before the installation of the fan unit!
The start-up delay is activated by switching on, e.g. in combination with the light switch. The overrun time is activated
by switching off.
If the dial is not set to the factory setting, normal operation will activate immediately. When test mode is running, the
fan can be activated without start-up delay using the switch input for demand-controlled ventilation (always the highest
stage for multi-speed units). When deactivating demand-controlled ventilation in the test minute, the fan will immedia-
tely switch off without overrun. This applies for a switch cycle within the test minute. The activation and deactivation of
demand-controlled ventilation within the test period will end the test period with the deactivation of demand-controlled
ventilation. If the switch input remains activated beyond the test minute, the fan will continue to run until the switch input
is deactivated and the subsequent overrun time is finished.
7.2 Functional description Fan unit ELS-VNC.. overrun and interval timer
Integrated overrun and interval timer. Optional start-up delay 0 or approx. 45 sec., optional overrun time approx. 6, 10,
15, 21 minutes, optional interval time approx. 4, 8, 12, 24 hours. The factory settings (6 minutes) can be set or changed
using the DIP switch on the circuit board (see Fig. 21 and 22).
The coding must take place before the installation of the fan unit!
Operation with push button only possible in connection with start-up delay of 0 seconds.
