*Select the on positions which add up to the multiplier.
The multiplier is always the closest number equal to half the quotient. This formula will
give you a 5:1 vernier knob adjustable timing range with the user desired time delay as
the middle of the timing range. The approximate maximum of any timing range the user
selects is always 2x the desired timing e.g. 2 x 180 = 360 secs. The maximum of the
selected range will be 360 secs. To determine the approximate minimum setting of the
timing range, simply divide the maximum setting by 5. e.g. 360/5 = 72 secs. Therefore, as
per our example, to get a time delay of 180 secs the switch positions will be as follows:
S1
Off On Off On Off Off On
User will have a time delay range of 72 secs - 360 secs.
SWUDC Timing Mode Operating Instructions:
The Amperite SWUDC Time Delay Relay operates in any one of four modes. These are
user selectable by means of setting S8 and S9 of the nine positions Dip Switch. The
modes and switch positions are as follows:
