The controller is capable of increasing the speed (frequency) to a maximum of 50 Hz. The rate of change is
governed by programming within the drive to reduce motor, pump, and equipment wear.
6.1.4 The minimum speed of the motor is also regulated by the controller. At very low rpm, the pump may be
moving too slowly to adequately distribute the oil in the pump reservoir. Damage to the pump may occur.
The minimum speed (frequency) is set at 15 Hz to protect the pump unit from oil starvation.
6.1.5 For more details on the VFD drive, the readings and fault status, refer to the WEG Drive supplement at the
end of this manual.
7. MicroCool IBEX - STARTING THE SYSTEM
START UP
7.1.1 Install UV bulb prior to start up. (If UV is provided)
7.1.2 The system must be primed and flushed before pressurization.
This removes any contaminants such as dirt, brass filings or
Teflon tape that have found their way into the system.
7.1.3 Turn on the water supply to the pump module. The inlet or low
pressure gauge should read at the very least 20 PSI (1.4 BAR)
indicated by the green area of the dial. If the water pressure is
not sufficient, do not try to start the pump. The water pressure
problem must be corrected first.
7.1.4 To prime the pump module turn on the power supply to the IBEX module, open the electrical enclosure,
switch the circuit breaker to the on position. Once the VFD indicates “RDY” and the PLC is illuminated,
press F3 and F4 simultaneously. This will start the prime sequence of 30 seconds. The pump is now ready
to be started.
7.1.5 To start the IBEX module press F1 (run in Manual). The pump module will now run, there must be between
20 PSI (1.4 BAR) and 90 PSI (6.2 BAR) of pressure available to the pump at all times. Note- should the
water pressure drop below the factory preset of 20 PSI, there is a 3 second delay before the system goes to
“FAULT”. Refer to section 9 to reset.
7.1.6 The pump motor RPM will ramp (increase) up to the maximum speed (50 Hz) to fill the system. Do not worry
if the pressure does NOT reach 1,000 PSI (70 BAR) at this time (during flush sequence).
7.1.7 Let the module run for 2-3 minutes making sure that there is a good flow of water running out the end of the
atomization lines. Lines may have to be flushed in groups, with larger systems, to ensure adequate system
flush.
7.1.8 When finished flushing, press F3 (Stop) to stop the pump module.
7.1.9 The system is now flushed and ready for the pressurization procedure.
