The Simplex day tank controller is based on a printed circuit board with fixed inputs and outputs. Integration for pump run signals and day tank alarm conditions are through output relays. Where signals for day tank alarms are required by multiple systems, then supplementary multi-pile relays may need to be added by the installer.

The Pryco day tank controller is based on wired relay logic with fixed inputs and outputs. Integration for pump run signals and day tank alarm conditions are through output relays. Where signals for day tank alarms are required by multiple systems, then supplementary multi-pile relays may need to be added by the installer.
The Tramont day tank controller is based on a printed circuit board with fixed inputs and outputs. Integration for pump run signals and day tank alarm conditions are through output relays. Where signals for day tank alarms are required by multiple systems, then supplementary multi-pile relays may need to be added by the installer.
Tank monitors are integrated into fuel system controls by 2 methods: (a) output relays for tank conditions, and (b) through a serial interface – ASCII via RS-232 or Ethernet.
Typical output relay functions are: high level, low level, tank leak, sump leak, pipe leak.
Typical serial information is: tank volume, temperature compensated volume, ullage – space available in tank, and temperature.
The basic Red Jacket pump controller allows for a 120 VAC input signal (which they call a hook signal) to activate the submersible pump. The Earthsafe duplex pump controller activates the controllers by providing this signal.
The basic Red Jacket controller provide motor protection, but lacks the following features that are often required of mission critical systems:
- local power disconnect switch
- manual mode switch in addition to its passive auto mode
- current sensor or other feedback demonstrating pump function.
The basic FE Petro pump controller allows for a 120 VAC input signal (which they call a hook signal) to activate the submersible pump. The Earthsafe duplex pump controller activates the controllers by providing this signal.
The basic FE Petro controller provide motor protection, but lacks the following features that are often required of mission critical systems:
- local power disconnect switch
- manual mode switch in addition to its passive auto mode
- current sensor or other feedback demonstrating pump function
The base controller also has a function for extended run shutoff after a 60 minute operating time. For mission critical applications, this function should be de-selected by the dip switch settings within the controller.
