Generac Power Systems H-100 Governor Speed Regulator Option Chart, ‹Remote Trending

General Information

H-100 Control Panel Technical Manual

•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.

-Dump & Hold — Same as Dump, but also hold throttle closed until frequency back in range.

•Engine Linearization — Selects engine torque to actuator position translation curve for Bosch Actuators.

0 = No conversion - torque = position

1 = Butterfly Actuator with minimum position same as unpowered actuator

2 = Diesel arm with Horizontal rod

3 = Diesel arm with Vertical rod

4 = Same as 1, but minimum position at actuator mechanical stop

5 = Same as 4, but with limited position resolu- tion of 1

6 = Same as 4, but with added energy to accom- modate throttles that normally operate in the nearly closed position at no load

•Integral limit/Antiwindup — Choose whether to use an integral limit or an anti-windup strategy.

YES = integral limit NO = anti-windup

•Limit/windup parameter — If “Integral Limit” is selected, this is the maximum value the integral is allowed. If “Anti-Windup” is selected, this is the integral value above which the anti-windup algo- rithm becomes active.

•Pwm Counts per ampx10 — Number of PWM counts required to drive one tenth of an amp into a linear current driven actuator. This only applies to the “Linear Current” actuator type.

•Desynch Offset — Offset of –0.9 to +0.9 Hertz to be applied to the target frequency to improve passive synchronizing by Automatic Transfer Switches. If an in-phase or synchronized transfer is required, use this setting to adjust the generator frequency to 0.1 Hz above nominal Utility frequency.

TRENDING

Just like in the PM-DCP, there are two types of trend- ing available - Remote and Local.

‹REMOTE TRENDING

GenLink performs remote trending by polling the controller for the selected data at the desired rate. Up to 8 analog channels can be monitored at a 0.3 second rate. If a faster rate is desired, reducing the number of analog channels monitored will allow for a

0.1second rate. The polling rate can be varied from

0.1seconds to several hours. GenLink can save the data to a file and/or display it as a near real-time graph. The file is MS Excel compatible ( CSV format ). Examples of things you can trend are the generator frequency response (in 0.1 second steps) to a block load or Generated power over a day.
