The annunciator digital output selection screen can be used to assign common built-in functions to the digital outputs. This page is shown below.
In some cases, the setup screen for a particular function will already have a box to select an output (For example, see "Idle Hold Setup").
However, for some functions, the only way to assign the output is through this screen. Also, this screen can be used to assign two outputs with the same function.
To assign an output to a function, select the output. A list of possible functions will be shown (including "None"), and the desired function can be selected.
Some outputs will be greyed out if they are hard coded to a particular function.
A list of possible options and what they do is shown below. If an option below doesn't show up in the list, the DCT and/or Brain likely need to be updated.
| Option | Description |
|---|---|
| LUBE | Powered on when the Pre/Post lube should be active |
| START | Powered when the start output is active. For Non-ECU modes, this runs a starter. For an ECU, this may be on the entire run time as a run signal to the ECU, depending on ECU type. |
| IDLE | Powered on during idle hold or idle switch selection. The output can then be wired to the idle/rated input of another ECU or speed controller |
| PRELUBE PERMISSIVE | Powered on when the prelube permissive is not yet met. Can be used for a lamp |
| WARNING LT | Duplicates the warning (yellow) segment of the light tower |
| SIREN | Duplicates the siren signal of the light tower |
| RED LT | Duplicates the red segment of the light tower |
| GREEN LT | Duplicates the green segment of the light tower |
| SHUTDOWN ACTIVE | Powered on during the ‘shutdown delay’ state. Can be used for a powered-shut fuel valve |
| SUCTION | Suction block valve |
| DISCHARGE | Discharge block valve |
| BYPASS | Bypass valve |
| BLOWDOWN | Blowdown valve |
| BATT SAVER | Battery saver active. Should be wired to kill the panel. |
| FAULT | Powered when in the faulted state |
| WARNING | Powered on when a warning is active |
| ADEM DER | Driven Equipment Ready logic to go the ADEM. Powered on when the system is clearing the ECU to start the unit. |
| FUEL VALVE | Duplicates the logic of pin 10 of the module. Powered on during normal run to allow for a fuel block valve. |
| START GAS SUPPLY | Start gas block valve |
| SPEED AUTO | Powered on when the speed is in the auto state |
| HOT START | Powered on when the engine is off but not faulted, for hot start |
| RESET | Reset broadcast, turns on briefly when reset is pressed |
| CYL OIL PUMP | Cylinder oil pump |
| SCRB DRAIN | Scrubber drain valve |
| COOLER VFD | Cooler VFD run, is generally on when the main motor is on but the start is staggered with a delay |
| IGNITION ENBL | Duplicates pin 9 of the annunciator, turns on when the ignition should be enabled |
| FLAME DET. FAULT | Powered on when any flame detect alarm is active |
| ASC RESET | Use output to drive ASC (Ariel smart compressor) reset pin |
| RUN STATUS | Output is powered on while the unit is running (according to RPM reading) |
| VALVE UNLOADER | Meant for a valve unloader, powers on the unloader when the unit is stopped or warming up. Powers off as soon as the bypass valve closes (end of load delay). |
| STOP PULSE | For a VFD that needs a pulse to stop this output asserts a three second pulse at time of stop. Note: for latch-shut fuel valves, use the option SHUTDOWN ACTIVE instead. |
| ESD CLEAR | Powered on when no ESD fault is active (which is most of the time) |
| LOAD ACTIVE | Powered on when the unit should be loaded (same time as bypass would close) and powers off during shutdown / unit off |
