Tulsa, OK, United States, 2009/03/04 - The Time Mark Model 42A Pump Controller is a versatile and advance liquid level/pump management system. The Model 42A can control up to 3 pumps with a 4-20mA input or 2 pumps with a 4-20mA input and backup floats.
Alarm inputs for seal failure, over temp, contactor fail and a spare (ex. 2nd seal fail) and an alarm output relay are provided.
The graphic display shows current depth, a liquid level graph with set-points, date/time and alarm status. Four buttons allow access to configuration settings (password protectable), pump status with run time meters, alarm status and real time alarm event logs with alarm type, date & time.
Alternation functions are built-in, and both 4-20mA input and retransmission 4-20mA output are scalable. The Model 42A comes standard with serial communications via RS-232 or RS-485 and a USB port reserved for configuration.
