2.4.3 Program Path 4 — Multi-Point

The following procedure must be follower if MULT

(multi-point) has been selected in Program Path 1 CNFG

(configuration). Probe calibration, Program Path 2, must

also be accomplished for the Multi-Point program to

operate. These two procedures, Multi-Point and Probe

Calibration, can be done in any order.

NOTE: Use the same unit of measure that was used in Probe

Calibration. Be consistent throughout the program.

Press ENT

to read DISP. Press the DOWN

arrow

key to display MODE.

STEP 1: DISP (Display)

1. Press ENT

to read DISP. The display will read the

actual process level, based on the unit of measure that was

used in Probe Calibration (PRLO/PRHI).

2. Press the DOWN

arrow key to display MODE.

STEP 2: MODE (Mode)

1. MODE refers to the configuration of both the control

mode and the fault mode. Press ENT

to display CNTL

(control). Control allows for selection of normal or

lead-lag pump control.

2. If this is the desired condition, press ENT

3. The next level of the menu will be displayed; the selection

of normal or lead-lag pump control. Choosing NORM will

allow normal operation of the relays. If lead-lag pump

sequencing is desired, press the DOWN

arrow key to

display LEAD.

NOTE: Selection of LEAD (lead-lag) affects relays 2 and 3 only and

does not apply to Model 822. LEAD must NOT be selected for

Model 822.

4. Once the proper choice is displayed, press ENT

display FALT.

5. Press ENT

to display DNRG (de-energize). In this

position, all control relays will de-energize (go to a fail-safe

state) when a fault is diagnosed.

6. Use the UP

or DOWN

arrow keys to toggle

between DNRG (de-energize) or IGNR (ignore). If IGNR is

chosen, all control relays will continue operating when a

fault is diagnosed.

7. Press ENT

to store the appropriate choice. The unit

reads RLY1.
