Operation

On Delay

When input power is applied to the MCS, the timing cycle begins. At the end of the timed period the load is energized. When input power is removed, the timing circuit is reset and the load is de-energized.

Physical Mounting: Ambient Temperatures Operating: 0°C to 65°C UL Operating: 0°C to 40°C Storage: -30°C to 85°C Notes: Remote Timing Resistors - multiples of 2.7 megohms will increase the time delay by 1 minute ±20%. For adjustment codes 3 & 4 a jumper or resistor must be installed across terminals 3 and 4 to allow the timer to time out.
