2.7 Electronic Unit
Remove housing lid to access status LEDs, time delay
adjustment, and conguration jumpers. See Figure 2-6.
2.7.1 Time Delay
  adjustment is used to avoid an oscillating relay
output due to agitation or waves in the vessel. The time delay
adjustment can be eld adjusted from 0 to 60 seconds. Unit is
shipped with time delay setting at zero seconds.
The Time Delay adjustment is a 270-Degree turn pot and is at
zero seconds when in the full counter-clockwise position. Do
not force the pot past the stop or damage will occur.
2.7.2 Time Delay Action
 describes whether the relay contacts are
delayed from going into the alarm state or recovering from an
alarm state.
• : delays system from coming out of alarm.
• : delays system from going into alarm.
• The instrument is supplied with time delay action set in
forward mode () position.
• Time delay action is eld-selectable using the Time Delay
Jumper located on top of Electronic Unit. See Figure 2-6.
