Features

• Selectable pump alternation when used with two pumps to minimize pump wear. With alternation “on” a seal failure or over temperature condition will force the non-failed pump to lead status and stop alternation.
• Alarms can be programmed for output indication of pump seal failure or over temperature.
• Selectable time delay, for pump two, on power up to prevent both pumps from starting at the same time. If power is lost, upon regaining power a time delay of up to 60 seconds can be selected to prevent too large of a current draw.
• In the event of power loss, upon regaining power a time delay of up to 60 seconds can be selected to prevent excessively large current draw
• Test system function that simulates the process input to ensure the pumps are operating or to test programming.
• User-friendly programming menu
