Digital and Relay Output Programming
EMCP 4.1 and EMCP 4.2 support relay outputs capable of 2A resistive at 30 VDC. The EMCP 4.1 has six "Form A" relay outputs (normally open). EMCP 4.2 has six "Form A" relay outputs and two "Form C" relay outputs (both normally open and normally closed).
EMCP 4.2 also support two programmable discrete outputs capable of sinking 300 mA per input. These outputs will sink a current to draw down a voltage of up to 30 VDC down to battery (-).
Outputs can be configured by using the EMCP 4 display. For some of the set points, level 2 or level 3 access is required. This section will assume that the correct level 2 or level 3 access has already been obtained. Alternately, Cat ET can be used to configure these outputs.
The programming of the digital and relay outputs starts by selecting a "Usage Type". The rest of the programming is dependent upon what usage type is selected. Illustration 1 summarizes the paths possible for programming digital and relay outputs.
Note: If the engine operating state is configured as hard wired, then "Relay Output #1" must be programmed to "Starter Motor Relay". And "Relay Output #2" must be programmed to "Fuel Control Relay".
