Design .01 with mechanical control can be complemented with initiation by means of an
electromagnet (solenoid). The voltage of the electromagnet (solenoid) can be AC 230V, AC/DC
24V. By voltage AC 230 V is damper equipped by electromagnet EM230. By voltage AC/DC 24
V is damper equipped by electromagnet EM230 with pre-pulse switch SIEM24. SEIM24 activates
the electromagnet after capacitor charge witch is placed inside of SIEM24. It takes about 10 sec.
Charging time depends on the current supply. For reliable operation is necessary connect to
electromagnet or pre-pulse switch appropriate supply for 20 to 30 sec. After activation of
electromagnet is released initiation lever and damper is closed. After activation is initiation lever
released. If is damper set up in position "OPEN" is necessary unlock initiation lever by pulling of
electromagnet core.
