Standby Activation Speed

The Standby Activation Speed is the speed representing a no flow condition of the pump preset at the fac-
tory. It can be determined by dead heading the lead pump and recording the pump speed. Refer to the VFD
Owner's Manual for additional details as setup instructions will vary. The parameter can be updated in the
VFD Parameter Screen 2 of the Master VFD Control HMI. Refer to
NOTE: Programming a Standby Activation Speed of 1-3 HZ above the value has the VFD go into
standby mode during no flow periods.
When the lead pump motor is operated at a speed lower than the Standby Activation Speed for a period of
time exceeding the Standby Mode Timer, the lead pump is taken off-line and placed in a standby status. The
lead pump will remain in standby until the Master VFD measures a pressure less setpoint minus the PID
Restart Error Level.
• Refer to the VFD Owner's Manual for additional details as setup instructions will vary.
• To set the Standby Mode Timer or the PID Restart Error Level via the Master VFD Control HMI, refer
to "VFD Parameter Screens 1 & 2" on page

Boost Function

A boost function can be enabled so that the lead pump will run at a higher speed for a period of time before
going into standby mode. This can be set up by programming a boost Speed Time for a value greater than 0
(this value is the seconds the boost will operate at) and setting the boost speed in the Preset Speed.
• Refer to the VFD Owner's Manual for additional details as setup instructions will vary.
• To activate the boost feature via the Master VFD Control HMI Menu, refer to
HMI Main Screen" on page

VFD PID Setpoint Pressure

• The VFD PID reference parameter represents the pressure transducer range.
• The setpoint pressure is calculated internally by the VFD by dividing Pressure Setpoint by Pressure
Transducer Range. Refer to
the Master VFD Control HMI Menu.
• Refer to the VFD Owner's Manual for additional details as setup instructions will vary for individual
drives.
• If a replacement drive is installed without this function block programming, the discharge pressure set-
point will need to be manually entered in the VFD. Refer to the owner's manual for instructions.

Pre-Start Verifications

1. Check electrical incoming voltage meets requirements and an adequate ground connection exists.
2. Inspect the overall system for damage during installation.
3. Pressurize the system with the site water to remove any trapped air.
4. If there are any water leaks in the piping, isolate the location and tighten the connections.
• If the leaks are at the threaded connections in the piping circuits, tighten each fitting so the suction
and discharge manifolds equally distanced.
