(10) Panel light switch (PLS) The electronic modular control panel II+ (EMCP II+) is located above the generator distribution housing. The control panel consists of the following components: a main panel with indicators, meters and control switches. This control panel may be equipped with optional modules in order to match the customers' needs and requirements.The left side of the control panel contains the Generator Set Control + (GSC+). This is the main component of the system. The GSC+ displays the following information: generator output, fault conditions and key engine parameters. The center section of the control panel contains switches and an optional alarm module. The right side of the control panel may be blank, or the right side of the control panel may contain the Synchronizing Lights Module or the Custom Alarm Module.The main control panel may or may not contain all of the components which are shown in Illustration 1. Some components are optional. The optional components may not be required for your particular application. Generator Set Control + (1) - The generator set control + (GSC+) is the main component of the EMCP II+. See the topic "Generator Set Control + (GSC+)" in this section.Engine Control Switch (2) - The engine control switch (ECS) determines the status of the control panel. In the AUTOMATIC position (3 o'clock), the engine will start automatically whenever a remote initiating contact is closed. The engine will shutdown after the initiating contact opens and after a programmable cooldown period has elapsed. The cooldown period can be programmed to give a 0 to 30 minute cooldown period before the engine shuts down.In the MANUAL START position (6 o'clock), the engine will start and run as long as the ECS switch remains in this position.In the STOP position (9 o'clock), the fuel solenoid shuts the engine down after a programmable cool down time period has elapsed.In the OFF/RESET position (12 o'clock), the fault lights are reset and the engine shuts down immediately.Start Aid Switch (3) - The start aid switch (SAS) is optional. The SAS is used to inject ether into the engine when you are starting the engine in cold weather conditions. When the SAS is in the ON position, the switch energizes the starting aid solenoid valve (SASV) and meters a specific amount of ether into a holding chamber. When the SAS is released, the solenoid releases the ether to the engine.
The engine must be cranking before using the start aid switch. Damage to the engine is possible if ether is released to the engine but not exhausted or burned by the engine when cranking.
Panel Lights (4) - Panel lights (PL) are controlled by panel lights
