Introduction

The Commander Series has three unique application configurations. The choice of application is

field selectable. The three configurations are:

• Multi-Tank Display (Application #1) – Commander will accept up to Four 4-20 mA input

transmitters and will provide a 3A SPST relay output for each input.

• Differential Level Controller (Application #2) – Commander will monitor the levels

above and below a rake and control a relay based upon the defined differential between

the two levels. In addition, a differential alarm can be programmed as well as individual

alarms for each input.
