Konus Burners, Primary, and Vat Pumps
along with an alarm on the panel view. This low flow could be caused
by plugged orifices, dirty filters, worn pumps, bad couplings, or
electric motor problems. Make sure all heat exchangers are
operating properly and that the proper primary and secondary loop
valves are open.
FS1 Float Switch
If the fluid level in the level tank drops below this switch, the system
will go into the emergency mode of operation. To refill the tank, the
FS1 and FS2 switches can be held in position, allowing the level
pump to deliver oil, until the oil rises above the FS2 level. The
switches should then be released. The tank can also be filled by the
fill/drain pump by opening and closing the corresponding manual
valves near the level and fill/drain pump.
FS2 Float Switch
When the oil level in the level tank drops below the setting of this
switch, the level pump is turned on. Once the FS3 switch is actuated,
the pump is turned off.
FS3 Float Switch
When refilling the level tank, the level pump will be turned off when
the switch is actuated.
GS1 - GS2 Gas Separators
These will permit the nitrogen in the oil to separate and be vented to
the top of the buffer and level tank. The nitrogen is then directed from
the top of the level tank back into the drain tank.
