Generic Pump Control Setup

When scoping a system, always check that dangerous over-pressure at the pump outlet will be avoided with the use of a VFD pump (with feedback connected!), an over-pressure release valve, or the pump feeds directly into a stand-pipe or ditch without risk of pressure buildup !!

System Components

Wildeye pump control consists of 5 components which should be installed into the pump panel as described below. 

Each component is discussed in more detail below.

24V DC Power Supply

For powering of the Wildeye, a 24V DC power module is preferred.

Wildeye supplies part ACC-PSU-DIN-120VAC-24V-5A if needed. If a 24C DC power source exists in the panel already it can be used if it has 3W surplus. 

Examples of 24V DC power modules in pump panels (Wildeye option shown on the right):

Wildeye 

Mount the Wildeye in a convenient position in the panel:

Current Transducer

Clip the Wildeye Split Core Currrent Transducer ACC-SEN-CS-SPLIT-200A-NO-A to the wire carrying power from the control panel to the pump:

Relay Control Module

Use the Wildeye Relay Control module to wire the pump such that a contact closure will activate the pump when the pump is set to "Auto" mode. 

Wildeye Relay Module 3-core cable:

Green = COM --> Connects to "S1"

Blue (previously white) = NO - "Normally Open". --> Connects to "SN" on Yaskawa

Red = NC   --> Do Not Connect

Example relay module attaching to Auto control line on Yaskawa P1000:

Hand/Off/Auto Monitor

If the pump controller is a VFD and does not have an Hand/Off/Auto (HOA) switch it is recommended that one is added. Otherwise when the VFD is placed into "Auto" mode for external control, it is not easy for operators to put it back into hand mode without navigating the meny screen to change settings. 

A hand/off/auto (HOA) switch should be added to VFDs:

Add Contact Blocks to the HOA for Remote Monitoring

Most HOA switches can be upgraded to have additional contacts added. 

It is highly recommended that the HOA has an additional pole added to allow the Wildeye to sense the position of the HOA switch. This allows the Wildeye to detect if the pump has been left in the wrong status and cannot remotely control the system. 

A 3PDT electrical diagram is shown below. The Wildeye HOA Monitor module should be wired to the "dry" or "voltage free" contact side:
