ELECTRICAL CONNECTIONS Units are supplied with 22 AWG free leads exiting from a ½”-14 NPT male conduit connection. The leads are-color coded and marked. See Figure 2 for AC operation and Figure 3 for DC operation. 4-20 mA output (option letter V) is connected to the 2-pin connector on the top-right of the unit per Figure 4, using the supplied mating connector. This mating connector has solder cups that will take wires as large as #18 AWG. See Chapter 4 for operating instructions. The R

CHAPTER 3 OPERATION & PROGRAMMING This section describes the regular (normal) operation of the TM Smart-Switch as it monitors pressure after installation and initial setup, and the Programming Mode for changing the settings. Both modes rely on the front panel for information and input. See Figure 6 on the next page. OPERATION MODE To begin operation, apply correct power to the appropriate free leads (there is no on-off switch). In normal operation mode, the display shows: • Online L

STANDARD VS. WINDOW MODE The terms “Standard” and “Window” describe two methods for TM setting up the Smart-Switch to monitor pressure. Standard Mode In Standard Mode, illustrated in Figure 8, the SP1i (or SP2i) set point actuates when the pressure being monitored goes above the TM set value. At this point, the Smart-Switch might turn off whatever electrical power is being applied to a pump, for example, which is increasing or maintaining the pressure. The switch de-actuates, or resets,

Deadband The deadband is the separation between the increasing set point and the decreasing set point, as shown in Figure 8. The deadband can be anywhere from 1% to 99% of Full-Scale Output (F.S.O.). TM In the case above where the Smart-Switch is controlling a pump, a wider deadband reduces the frequency at which the pump cycles on and off. Window Mode This mode is useful when you want to maintain pressure within a certain range, and want to be notified when pressure either goes above
