Fan timer relay 24 24 V AC V DC (max) Metz Connect 11028313 1 pc(s)
The fan timer relay was designed specifically for controlling two-stage motors. On and off delay are separated and continuously adjustable. It is controlled via a two-stage switch. The motor contactors are controlled with both mutually locked outputs. How it works:, 1. When selecting level 2 directly, level 1 is first switched on for the set start-up time so that the fan can run up to the rated speed. Then it is activated in level 2.2. When switching from level 2 back to level 1 or FROM position OFF, a power-off delay is triggered so that the fan can only spin out before level 1 is activated.3. If stage 1 is already switched on for at least the set start-up time, the switch-over in stage 2 is immediate. When switching from level 1 to 2, the interruption may not exceed 250 ms. If this time is exceeded, the procedure is as described in point 1.This text is machine translated.
