9.2 Booster Starter Control Box<br />
9.2.1 Motor Control The motor control circuit has a local <strong>and</strong> remote selector switch, with<br />
local <strong>and</strong> remote emergency stop-lock <strong>and</strong> start switches <strong>and</strong> mains indicator lights. The motor<br />
is wired in a star-delta configuration, starting in a star connection <strong>and</strong> changing to delta<br />
connection after approximately 8 seconds. Upon starting the booster running light illuminates<br />
<strong>and</strong> hours of running are recorded on an hour meter.<br />
9.2.2 Moisture Dump/Unloaders Upon starting the booster, a timer T1 sets the period that<br />
the booster runs unloaded <strong>and</strong> dumping moisture. T1 is pre-set, usually to 10 seconds<br />
(maximum 30 seconds). A second timer T2 sets the period between unloading during running .<br />
T1 additionally controls the initial period that the booster runs unloaded <strong>and</strong> dumping moisture.<br />
9.2.3 Main Fuse Switch <strong>and</strong> the Reset Button The main switch isolates the compete circuit<br />
from the power supply. After switching on, the reset button must be pressed <strong>and</strong> the fault lights<br />
extinguished before the motor can be started.<br />
9.2.4 Fault Lights The fault lights indicate low oil pressure, high gas temperature, <strong>and</strong> high<br />
gas pressure. In the event of low oil pressure, or high gas temperature/pressure in the 1 st or 2 nd<br />
stages the appropriate switch will open <strong>and</strong> stop the booster. The particular fault will be<br />
indicated locally on the control panel, but remotely only one fault light exists.<br />
9.3 Storage<br />
9.3.1 The booster is normally supplied uninhibited. If there is likely to be a long delay<br />
between installation <strong>and</strong> commissioning (in excess of six months) it can be inhibited prior to<br />
delivery. Consideration must also be given to this if the system is to be unused for a significant<br />
period (see chart overleaf)<br />
