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.

Connections
The MCS operates with the Load in series
with the timer. A Load must always be
connected in series with the MCS to avoid
damage.

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.
