GENSYS COMPACT PRIME

All-in-one synchronizing and paralleling controller

The GENSYS COMPACT PRIME is made for generators used in Power plant applications requiring

synchronizing, active and reactive load sharing and electrical/mechanical protections.

GENSYS COMPACT PRIME offers flexibility and time saving thanks to its simple wiring, all features included

(no option), and easy engineering and programming.

Hardware and Display

GENSYS COMPACT PRIME is available in both switchboard panel mounted version with display, or core base

mounted version. GENSYS COMPACT PRIME is also compatible with i4Gen touchscreen color display.

Software

GENSYS COMPACT PRIME is configurable from its front panel display, from i4Gen, or through the free CRE

PC software: CRE Config Software.

Button inhibition

To inhibit front panel buttons, use the CRE Config Software/System/Button inhibition page. This page shows

the list of front panel buttons, tick the corresponding box to inhibit actions on the button.

Table below shows the 16 bits variable used for remote button inhibition by Modbus, each bit is assigned to a

button:

Variable Label Description

[3557] Inhibit key Each 1-bit inhibits a front panel button.

Relation button/inhibition bit [3557]

External button requests

It is possible to remotely activate button actions by Modbus TCP, for a remote manual control for example.

If a button action is controlled by Modbus TCP, the last request received (external or from the front panel) is

treated in priority and cancel the previous request.

MAN / AUTO: If the 2 modes are requested, the MAN mode request cancels the AUTO mode one.

The buttons on the front panel can be replaced by external commands via digital inputs.
