JOHNSON CONTROLS
109
(Optional) A harmonic filter that limits electrical power supply distortion from the variable
speed drive in order to help the building comply with the guidelines of IEEE STD. 519-
2014 shall be provided. The filter shall be unit mounted within the same NEMA 1 enclo-
sure and shall be UL listed. The following digital readouts shall be provided at the chiller
unit control panel as part of the filter package:
• Input KVA
• Total power-factor
• 3-phase input voltage
• 3-phase input current
• 3-phase input voltage total harmonic distortion (THD)
• 3-phase input current total demand distortion (TDD)
• Self diagnostic service parameters
Separate meters for this information shall not be acceptable.
FACTORY-INSTALLED COMPRESSOR MOTOR STARTER [OPTION THROUGH 900
HP (671 KW) 200 600 VOLTS]
The chiller manufacturer shall furnish a reduced voltage Solid-State Starter for the com-
pressor motor. Starter shall be factory mounted and wired on the chiller. The starter shall
provide, through the use of silicon-controlled rectifiers, a smooth acceleration of the motor
without current transitions or transients. The starter enclosure shall be NEMA 1, with a
hinged access door with lock and key. Electrical lugs for incoming power wiring shall be
provided.
Standard Features include: digital readout at the OptiView™ Control Center of the follow-
ing:
