All KI and KIV units have a standby delay timer which will shut the compressor off if it has been operating
unloaded for a set period of time. The unload timer is adjustable. See Description of Operations / Display
and Controls manual to set this timer.
1.7 Maximum Operating Pressure with Standard Motor
CAUTION
DO NOT exceed motor nameplate Service Factor amps at 100% capacity. Failure to follow
this caution may result in damage to the drive motor.
Maximum operating pressure is limited by available motor power and the safety valve setting. Because of
the many available air end, sheave and motor combinations it is not practical to define all combinations.
When resetting operating pressures adjust pressure upward while observing an ammeter reading on all
phases compared to motor nameplate limits. See Table 3.
