Motor Run Monitoring Signal (3-wire transformer)
Level Sensing Transducers
A TCU using the pump control process can accommodate two different types of input-supported transducers.
• Digital-type devices such as contact closures, float switches, and pressure switches
• Analog-type devices that are either analog current (4-20 mA) or analog voltage (0-5 V)
Floats
The input terminals for the contact closure devices are:
LOW_LVL (P2-6)
OFF_LVL (P2-7)
LEAD_LVL (P2-8)
LAG1_LVL (P2-9)
LAG2_LVL (P2-10)
HIGH_LVL (P2-11)
