TIME RELAY "MIXER" - VRM
	It is designed for cyclic reversing three phase motors (ventilation, mixers, etc.). It has two relay outputs. They are used for turning on contactors for right (K1) and left (K2) direction. On the front panel there are potentiometers for adjusting rotation time (T1) and pause time (T2). One cycle consists of right turn, a pause, left turn and pause, next cycle starting with right turn again. Time ranges of T1 and T2 can be any combination of standard times or times requested by the customer.
PHOTO RELAY- FR
	It is used for automatical switching on/off outdoor lights, street advertisements or other consumers, depending on the ambient (day/night) light intensity. The intensity of light at which the relay will react is adjustable by potentiometer on the front panel. Response has delay time of about 30s, to avoid reaction at short term changes in light. For testing purposes, and settings during installation this time can be eliminated by placing a jumper on the box top. Relay contacts: 5A/220Vac.
PULSE RELAY
	It acts as electromechanical bistable relay. Pressing the external push button switches relay on. Next press causes the release of the relay and so on. It is used for turning on/off lights in long corridors, alternating between two motor drives so they wear out equally during the operation, and so on. Two LEDs on front panel indicate relay status. Power supply: 230Vac or 24Vac/dc Consumption: 2VA Contact rating: 5A/230Vac
