Load Generator (Terminal 37)
The input switch or relay contact used to activate the Load Generator command
connects to terminal 37. This discrete input will cause the Load Control Function
to ramp to a distinct mode of operation. If the state of the input is “TRUE”, the
Load Control Function will increase or decrease in order to achieve either
Isochronous Load Sharing or Base Load operation. If the state of the input is
“FALSE” (input switch or relay contact open), the Load Control Function will
increase or decrease in order to achieve the Unload trip level. The CB Aux/Droop
Contact discrete input must be “TRUE” for the Load Generator input to affect the
control.
Base Load (Terminal 38)
The input switch or relay contact used to activate the Base Load command
connects to terminal 38. This discrete input will cause the Load Control Function
to operate in Base Load. In this mode of operation the governor will control the
load on the generator. The utility (main) bus or an isochronous generator set
must control the bus frequency while in Base Load operation. With the state of
this input “TRUE”, isochronous load sharing with other units is disabled. With the
state of this contact “FALSE”, isochronous load sharing with other units can
occur. The CB Aux/Droop Contact discrete input must be “TRUE” for the Base
Load input to affect the control.
Actuator Output
The actuator wires connect to terminals 13(+) and 14(–).The current range to the
actuator output is configured in software for a 0–200 mA or 0–20 mA actuator.
The software configuration also allows for selection of Forward or Reverse acting
actuator. Use shielded wires with the shield connected to terminal 15. Do not
connect the shield to the actuator or any other point. The shield must have
continuity the entire distance to the actuator, and must be insulated from all other
conducting surfaces. Refer to the manuals listed in the “References” table for
additional information on actuator installation.
Analog Inputs
Both Analog Inputs can be configured for several different functions depending
on the application needs.
1. Not
Used
2. Remote Speed Set Point
When the control is in remote droop or isochronous mode the Remote
Speed set point moves the Speed Ramp to the same value as the Remote
Speed set point,
3. Baseload Set Point
When the control is in Remote Base Load mode the Remote Load set point
moves the Load Ramp to the same value as the Remote Load set point.
