Chapter 5.
Operational Description:
Single Unit Parallel
G
Single Unit Parallel operation of the EGCP-2 control enables the control’s ability
to synchronize and close to the mains. When paralleling to the mains, the EGCP-
2 will operate in either a base load (constant generator KW), or process control
modes, depending on which switch inputs are received at the control. The
EGCP-2 will also operate in a Power Factor or VAR control mode while in
parallel with the Mains if the VAR/PF control setpoint in the Reactive Load
Control tuning menu is set for either PF control or KVAR control.
The EGCP-2 may also be configured for soft transfer operation. Soft Transfer
operation is enabled in the configuration menu item labeled “Load Control Mode”.
Setting this item to “soft transfer” will enable the soft transfer capability of the
control. Soft transfer refers to an operating mode in which the generator
assumes load (either base load or process), and upon reaching a specific base
load or process reference point, issues a command to open the mains breaker.
This effectively transfers load from the mains to the generator in a smooth
fashion.
The key configuration points in the EGCP-2 software which need to be
configured for Single Unit Parallel operation are:
Configuration Menu:
Number of Units: Single
Operating Mode: Mains Parallel
Real Load Control Menu:
Load Control Mode: Normal or Soft Transfer (depending on
application)
Transfer Switch Menu:
Check Mains Breaker: Enabled
If this is to be a standby power unit, which will close to the load on loss of mains,
program the following setpoints as required by the system for reliable Loss of
Mains Detection. Not all these setpoints have to be set for loss of mains
detection, only those that pertain to detecting loss of mains for each particular
application or system.
