I NTRODUCTION The H-100 Control P anel is an electronic control box that functions as an advanced standby generator controller . Its technology is based on the flagship PM- DCP system with all its flexibility included. A familiar user interface in the form of GenLink®-DCP is used to program, monitor and change the parameters in the unit.
3 TH E M EA SU R EM ENT "ENGI N E" The measurement “engine” is the key feature of the system. All the inputs to the controller are processed by this module. Each physical input is measured and the result processed by an individual set of rules that are set via a PC and GenLink.
4 Where x can be: 1. THERMISTOR 2. CURRENT 3. LINEAR 4. PRESSURE 5. UNAL TERED 6. POL Y_3RD 7. POL Y_2ND 8. POL Y_1ST 9. POL Y_1ST_N1 10. POL Y_1ST_N2 11.
5 IMMEDIA TE = Alarms/W arnings with this qualifica- tion only become active immediately after the engine has started. Sensor Failure Check When this field is set, the input sensor is checked for short circuit or open circuit failure. Normally each of the inputs are conditioned externally to be 4- 20mA current loops.
ENGI N E MANA GEM ENT The engine management module is very similar to that used in the manufacturer's other products. It controls engine cranking, engine starting , engine running and engine stopping . These functions are performed to a set of “rules” that can be customized via parameters from GenLink.
S T ARTING AN D ST OP P I NG - SEQUENCE DIAGRAMS Remote start contacts CLOSED? Start the Engine At load accept limits? Warm up timer expired? Issue load accept signal Remote start contacts OPEN? Coold.
V OL T A GE R E GU L A T OR (OPTION) All panels include automatic voltage regulation as standard. There are various settings that can be made to the voltage regulator via GenLink. The set - tings are normally factory preset and are shown here for completeness.
Dump Enable — Indicates if extra load dump gov- ernor compensation is desired to reduce increase in frequency caused by drop in load. The following three selections are available: - No Dump — No additional compensation. - Dump — Reset governor algorithm when load dump detected.
L OCAL TR EN DI NG Local trending is done inside the controller where up to 1000 samples can be stored in memory . GenLink provides an interface to select the analog channels to be trended, the rate to be sampled at, and optional triggers to be used to specify when to sample.
Generator control is limited to the following output options (referred to as “Hooks”). 1. Use Keyswitch 2. F orce Off – cleared with “Use Keyswitch ” hook 3. F orce Manual – cleared with “Use Keyswitch ” hook 4. F orce Auto – cleared with “Use K eyswitch ” hook 5.

Press the button. Press the “ENTER ” button. This is a typical first engine parameter page. The three values on this page are not able to be configured as other values. LINE 1: Oil T emperature (Analog Channel #1) in degrees F ahrenheit. LINE 2: Oil Pressure (Analog Channel #3) in pounds per square inch.
S T A TUS There are two System Status pages. These pages show the system status, system time, and system versions. Do the following to view the system status pages: Press the “MENU” button. Press the button twice. Press the “ENTER ” button.
“W armed Up, Alarms On ” Generator is started, warmed up, and the hold- off alarms are enabled. “Running ,cooling down ” Generator is still running, but waiting for cool down timer to expire. “Stopping” Generator is running down after being turned off normally .
Each line displays a maintenance item that has been set up via GenLink. The value displayed is the approximate % of life remaining before maintenance should be performed. Refer to the Maintenance setup using GenLink. Press the “ENTER ” button. This is a typical third Maintenance Status page.
This is a typical first Generator P arameter page for a single phase system. LINE 1: Phase titles for the voltage and current – voltage title/current title. LINE 2: Line -to -Line voltage for AB and Line -to - Neutral voltage for A and B in V olts RMS.
This is a typical first System Diagnostics page. It dis- plays ten of the discrete inputs into the H-100 Control P anel. Inputs to the controller are internally pulled to 5 v , so to activate an input you must short it to ground.
Press the “ENTER ” button. Press the “ENTER ” button. The above two pages are typical of communications diagnostics, one page for each port. The LCD display will show four lines of information about the port: LINE 1: W ill show the type of port protocol that has been selected.
This is a typical third Internal Exercise and HTS page. LINE 1: The left side shows the HTS switch number that the data on this page applies to. This field is editable in that switch numbers 1 – 4 can be selected.
23 23 page also selects the switch to use for the Left Display Switch Mimic diagram if that switch is enabled. In addition, it is the selected switch number for the pre - vious page, and for the remote annunciator lights for generator power and line power .
The event log, as its name implies, is designed to store events which are programmable from GenLink. Each measurement channel or output function can be set as an event along with a setpoint.
