Miscellaneous Start Permissive

From EMIT Controls

Overview

The Brain (annunciator) has the ability to add a generic start permissive which specifies a sensor condition must be met before the start sequence will commence. After the unit is running, the permissive no longer needs to be met until the next startup.

Requirements

  1. The Brain (annunciator) should be updated to 1303 or newer
  2. The DCT should be updated to 1.19.109 or newer OR the EIM should be updated to 2.21.63 or newer
  3. The sensor needed for the permissive should be configured as a normal Brain/annunciator input. It doesn't need to have an alarm set up, but optionally can have an alarm.

Adding the Permissive

1. On the EIM, navigate to “Annunciator” -> “Annunciator Setup” -> “Outputs Setup” -> “Misc Start Permissive”. If using a DCT, navigate to “Settings” -> “Brain” -> “Outputs Setup” -> “Misc Start Permissive”.

2. Select the button next to ‘permissive’ and choose the sensor, threshold, and above/below. The condition entered specifies the value required to be met to start the engine. In the below example, the L Manifold Temp must be below 400 to start the engine. Aka if it is above 400 it will not start. Note: This shows the EIM screen, but the DCT screen for this setup is very similar.
