9.2 Lead/Lag
Control.
Similar to the central control box, a pair of compressors may be controlled by
a lead/lag control box, equipping the package with ‘lead / lag’ capability.
Lead/Lag
controls allow two compressors to operate in tandem. One unit is
selected to be the lead unit and the other the lag unit. In this situation, the
lead unit will provide the base air supply for the plant requirement. The lag
unit will provide any additional air as required during peak demands. The lead
and lag functions should be alternated between the two units by regularly
reversing the selector switch on a periodic (daily or weekly) basis.
9.2.1 Lead / Lag Control Box Operation.
The lead / lag control box offers lead / lag only in which to operate the two
compressor units. (Refer Fig.6):
Fig. 6 - Control Panel, Lead/Lag Control Box
The ‘Lead A / Lead B’ selector switch determines which compressor will
supply the base air supply for the demand. As stated above, the Lead and
Lag functions should be alternated between the two units by regularly
reversing the selector switches on a periodic (daily or weekly) basis.
Individual Start / Stop selector switches enable electrical isolation of the
motors only of one or both units.
