ADJUSTMENTS
Adjustable Delay on Make and Delay on Break
Timer
The potentiometer is used to select Delay on Break time
from 30 seconds to 5 minutes. Delay of Make (DOM)
timing on power up and after power interruptions is
equal to 2 minutes plus 10% of Delay of Break (DOB)
setting:
0.5 minute (30 seconds)
DOB = 123 second DOM
1.0 minute (60 seconds)
DOB = 126 second DOM
2.0 minute (120 seconds) DOB = 132 second DOM
3.0 minute (180 seconds) DOB = 138 second DOM
4.0 minute (240 seconds) DOB = 144 second DOM
5.0 minute (300 seconds) DOB = 150 second DOM
During routine operation of the unit with no power
interruptions the compressor will operate on demand
with not delay.
Typical Settings for Dual Unit Installation:
Unit 1: DOB set at 2 minutes, and DOM is 132 seconds.
Unit 2: DOB set at 4 minutes, and DOM is 144 seconds.
PRESSURE SERVICE PORTS
Liquid and suction pressure service ports are installed
on all units so that the system operating pressures can be
observed. Pressure chart can be found later in the
manual covering all models. It is imperative to match
the correct pressure chart to the unit by model number.
