DG SYSTEM MODE DESCRIPTION
6.1
SYSTEM MODE
6.1.1
MANUAL MODE
When manual mode signal is active, the system will work through manual mode. In this mode, HMC6
controller can only monitor data and alarm information but cannot control switch or engine. In addition, GOV
and AVR do not work but the manual governor IN, manual governor OUT, manual VOLT IN and manual VOLT
OUT do work in this mode.
6.1.2
SEMI-AUTO MODE
Semi-auto mode is activated by pressing
key; Semi-auto means that the unit will not initiate any
sequences automatically, as is the case with the auto mode. It will only initiate sequences, if external signals
are given.
An external signal may be given in three ways:
1. Push-buttons on the display are used
2. Digital inputs are used
3. Modbus commands are used
In semi-auto mode, all available diesel generator units can be started/stopped/synchronizing
closed/unloaded open upon push-button commands on the front panels for each generator.
The system monitors that if the generators are overloaded. Should that be the case, the Non Essential
Load (NEL) trip will activate to maintain power supply to the main busbar.
If a heavy consumer is requested, the system calculates the power needed. If the available power is
insufficient, the heavy consumer connection will not be allowed.
Semi-auto Start
：
a)
Start command will be initiated by HMC6 after pressing button
. The system enters into “Start
Output Delay” while the start relay will activate;
