Use to set the alarm level, coil status and latch status for the Low and High
relays (Fault Alarm is fixed).

The following table describes the default settings for the sensor.

Table 4:

Default Relay Settings

Setting Relay Options

There are two settings for Relay Options: Low and High. The Fault Relay is
fixed as Energized/Non-latching and cannot be changed. The low alarm level,
coil energization and latch status for low alarm are set first; high alarm level,
coil energization and latch status for high alarm are then set. All ranges are in 10
to 25%. Low Alarm levels and High Alarm levels will display if reached.

Step 1:

When

displays press the Calibration

Button or use the Reed Switch to select.
The flashing

YES

confirms the selection.

Step 2:

The message

Set Low

displays. Low alarm set-points are displayed

in increments of 1, beginning at 10 and

cannot be set above 20.

Step 3:

When the required level displays, press the Calibration Button or
use the Reed Switch to select.
The level chosen will flash to confirm the selection.

Step 4:

The message

Coil Status

displays. The display then shows

Energized YES?

and then

De-Energized YES?

Step 5:

Press the Calibration Button or use the Reed Switch to select.
The flashing

YES

confirms the selection. If no selection is made, the

Coil Status option is repeated.

Step 6:

The message

Latch Status

displays. The display then shows

Latching YES?

and then

Non-Latching YES?

Step 7:

Press the Calibration Button or use the Reed Switch to select.
The flashing

YES

confirms the selection. If no selection is made, the

Latch Status option is repeated.

Step 8:

The message

Set High

displays.

The High Alarm level

must be set between 21 and 25

. The High

Alarm level is displayed in increments of 1 beginning at the Low
Alarm set-point (as set in Step 3).

Step 9:

Repeat Steps 4 through 7 to complete the High Alarm level, coil
and latch status settings.

Note:

If no selection is made, a 5 minute timer expires, in which case the unit
returns to normal operation.
