Sigma Controls Myriad TPC LITE Instruction Manual page 3

INTRODUCTION:
The Sigma Myriad TPC LITE (Triplex Pump Controller) is a state of the art microprocessor
based, user configurable instrument for the monitoring and control of up to three (3) constant
speed or up to three (3) variable speed driven pumps.
The Myriad TPC LITE performs all of the functions found in a full size control panel.
 Displays level in numeric and bargraph forms
 Displays pump call status
 Allows full user selection of all system variables
 Monitors critical alarms (motor overtemperature, etc.)
 Monitors non critical alarms (seal leak, etc.)
 Monitors hand off auto selection switch position
 Monitors pump (VFD) 'run' feedback
 Provides digital and relay outputs for pump control, level alarm, sensor fail, and pump
fault.
 Permits user selection of pump sequence, alternation, and permitted quantity of pumps to
run
 Provides 4/20MA outputs for VFD speed setting and proportional control
 Provides time and date 'stamped' alarm information
 Audible and visual alarms
 Allows simulation of level to exercise pumps or verify operation
 Records "MAX" and "MIN" process values and a graphic trend chart for trouble shooting
 Available in ¼ DIN panel mount or Nema 4X enclosures
 'WATCHDOG' indicator for processor activity
