7.4.3 Choosing break/make contact relay type

Note: If the controller type “oFF” is set, the parameters listed in 7.5.3, 7.5.4, 7.5.5 and 7.5.6 are blanked

out.

This mode lets you determine the relay-state under Non-Alarm condition – dEEN (de-energised) or EN

(energised).

1) Follow directions in 7.6.2 to enter Controller mode.

2) Press the ENTER key. Scroll until the lower display shows “rEL”

and the upper display shows the current selection (de-energised =

dEEN or energised = EN).

3) Press the ∆∆ or ∇∇ keys to choose de-energised or energised

relay state.

4) Press the ENTER key to confirm your selection.

5) Continue with Advanced Set-up mode procedures, or return to

Measurement mode by pressing the ∆∆ and ∇∇ keys simultaneously

(escape).

7.5 Measurement Range sub-function

In this sub-function, the appropriate range is selected with the appropriate cell constant.

7.5.1 Selecting the Measuring Range sub-function

1) Enter Advanced Set-up mode. Push the ENTER key and scroll to

Advanced Set-up security code “22”. Push the ENTER key again.

2) Press the ∆∆ or ∇∇ keys to scroll until the upper display shows

“rng”.

3) Press the ENTER key. The upper display shows the maximum

measurement range, while the lower display shows the Cell constant. In

the lower left-corner of the LCD, the number corresponding to the

respective range is displayed.

4) Press the ∆∆ or ∇∇ keys to select the correct range. (Please refer to

Appendix 2 for the full list of measurement ranges).

5) Proceed to 7.8 to set current output or return to Measurement mode by pressing the ∆∆ and

∇∇ keys simultaneously (escape).
