Section D - Power Up, Functional Verification and Adjustment

Before Appling power to the instrument, it is recommended that a third party inspect the installation workmanship. Make sure wires are not pinched

or frayed. Check for matching serial numbers on the sensing element and the control circuit. Verify that the power and alarm circuits are properly

connected. Review the instrument configuration and its application.
On instruments powered by 100 –240Vac or 24Vdc/Vac, the power indicator is a green rectangular LED and the alarm indicator is a red rectangular

LED. On instruments powered with two wires (loop power), power is indicated by either one of the red LEDs at the edge of the control circuit. The

bottom LED (closest to control circuit) is the flow/wet indicator and the top LED is the no-flow/dry indicator.
Apply power and look for the power indicator light. After power is established let the instrument warm up for 5 minutes. Run the process at normal

and then at abnormal conditions. In most cases the instrument will detect a flow or level alarm with the factory settings. If the Instrument does not

respond, responds slowly or the alarm responds opposite to the required indication, proceed to the section pertaining to the type of control circuit

provided. Refer to Figure 12 and 13 to familiarize yourself with the location of the adjustment potentiometers and jumpers.

Adjustment by Observation - Input Power, 100-240Vac 24Vdc/Vac
The following instructions are for both flow and [wet/dry] applications. NOTE: Do not adjust R26 located between the green LED and the edge of the

control circuit.

Detecting Decreasing Flow or [Dry] (Low Flow/[Dry] Alarm, jumper at J2)

Run the process at normal flow [raise the level]. If the alarm status LED is off, turn the set point adjustment potentiometer (pot) R1 clockwise until

LED turns on. With the LED on, slowly turn the pot counterclockwise until the LED just turns off. Adjust the pot one-quarter turn counterclockwise

past the point where LED turns off. Stop the process flow [lower level]. And verify that instrument has switched to the alarm state.

Detecting Increasing Flow or [Wet] (High Flow/[Wet] Alarm, jumper at J1)

Run the process at normal flow [lower the level]. If the alarm status LED is off, turn the set point adjustment potentiometer (pot) R1 clockwise until

LED turns on. With the LED on, slowly turn the pot counterclockwise until the LED just turns off. Adjust the pot one-quarter turn counterclockwise

past the point where LED turns off. Increase the process flow [raise level]. And verify that instrument has switched to the alarm state.

Adjustment by Measurement - Input Power, 100-240Vac 24Vdc/Vac
The following instructions are for both flow and [wet/dry] applications. Verify that the mode jumper is in the operation position (J3). Attach a DVM

to TP1(+) and TP2(-). Establish a normal flow [wet or dry] condition, letting the instrument stabilize. Record the TP1 to TP2 voltage. Go to one of the

following procedures as applicable.

NOTE:

Do not adjust R26 located between the green LED and the edge of the control circuit.
