3 Wiring Instructions
WARNING – the E/One Alarm and Control panel is a high voltage system that controls power to an electric
motor(s). Care should be taken whenever performing service on the panel to avoid the risk of electrical shock
and/or damage to property. Because power may be supplied by multiple sources, circuit breakers alone may
not be sufficient to provide adequate protection.
The E/One PLC Quadplex panel wiring can change from model to model. All wiring shall be done in accordance with the
wiring decal on the inside cover of the panel enclosure. Typical wiring can be found in the Appendix of this manual.
4 Startup
The E/One PLC Quadplex Panel should arrive from the factory ready to operate. The panel is properly installed and
started by following the steps below.
1. Mount and wire the panel per the instructions on the enclosure door.
2. Ensure that Pressure transducer in the station is set at the appropriate height (10” from the bottom of the tank).
If it is not, the off level will not be at the correct height, and the system may not function properly.
WARNING – Pressure transducer must have a range of 0-2.5m to ensure proper operation. If a different range is
used run levels will be improperly scaled.
3. ‘Cold Start’ the panel – refer to Cold Start section of this manual for more information.
4. Clear the Alarm History – Refer to the Alarm History Log section of this manual for more information.
5. If other than factory default settings are required, set all limits and levels. Factory defaults settings can also be
restored via the user menu. (Refer to the User Programmable Options
section of this manual for more on this
feature).
