Time Delay Range
A: .1 sec. to 15.5 secs.
B: 10 secs. to 25 mins.
C: 10 mins. to 25 hrs.
D: 30 mins. to 77.5 hrs. Off
*Choose the range which most narrowly incorporates the time delay you desire. e.g. for
180 secs. Choose range B and set S1 to Off and S2 to On.
2) Calculating The Multiplier For The Desired Time Delay
Dip Switch positions S3 - S7 are used to set the multiplier which will customize your
time delay range. The values for these settings are as follows:
Switch Position Multiplier Value
S3
S4
S5
S6
S7
The Formula
Once you have chosen the appropriate basic timing range, perform the following
calculations - (to clarify the steps use the desired time delay of 180 secs. as an example):
A) For 180 seconds select range B (10 secs. to 25 mins.).
B) Divide the desired time delay (180 secs.) by the minimum time of the selected range.
(minimum time in range B is 10 secs.) 180/10 = 18. Always convert to the same time
units (min., sec., hrs.) when dividing.
C) The multiplier is equal to 1/2 of this quotient - 180/10 = 18. 18/2 = 9, therefore the
multiplier for 180 seconds is 9 and the user must set switches S3- S7 as follows:
Total = 31
