Timing Of Outputs
The timing of outputs is calculated by the time base and a multiplier. These two values play
different roles depending on the polarity selected. When programming outputs to pulse, both
the "On" and "Off" times can be set. One shot polarities can be programmed to operate
between 200 ms up to 99 hours in duration.

Table 103: Time Base Settings
The time base settings can be set to only one of the values listed in "Table 103: Time Base
Settings". The multiplier value is a two digit decimal number from 00-99. For greater
accuracy, use 60 seconds for 1 minute intervals and use 60 minutes for one hour intervals.
Pulsing Polarities
When calculating pulsing polarities both the "On" and "Off" times need to be programmed.
The duration or "On" time of an output is determined by selecting only one of the time base
options from "Table 103: Time Base Settings". This means there are only four "On" times to
choose from.
The "Off" time is calculated as a multiple of the "On" time by choosing a decimal number
between 00 and 99. If an output is required to operate for 200 ms every five seconds, program
the time settings as follows;
