Operating Instructions αlpha-RES1000
16
1) Follow directions in 7.4.1 to enter Controller mode.
2) Press the ENTER key. The upper display shows the current controller type and the lower display
shows “tYP”.
3) Press the ∆ and ∇ keys to select your controller type.
- L.Ct = limit value pickup (on/off control).
- oFF = controller off.
- PLC = pulse length control.
- PFC = pulse frequency control.
4) Press the ENTER key to confirm your selection.
5) Proceed to 7.4.3 step 3, or return to Measurement mode by pressing the ∆ and ∇ keys
simultaneously (escape).
7.4.3 Choosing break/make contact relay type
Note: If the controller type “oFF” is set, the parameters listed in 7.4.4 and 7.4.5 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 7.4.1 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).
7.4.4 Selecting proportional range value Xp
Note: If the controller type “oFF” or “L.Ct” is set, the parameters listed in 7.4.4 and 7.4.5 are blanked out.
This mode lets you set a band as a percentage of its full scale value. You can select this range from 10
to 200%, and the lower display shows “PrP”.
1) Follow directions in 7.4.1 to enter Controller mode.
2) Press the ENTER key. Scroll until the upper display shows the
proportional range (a number from 10 to 200%), and the lower
display shows “PrP”.
3) Press the ∆ and ∇ keys to choose the proportional range value
Xp.
4) Press the ENTER key to confirm your selection.
5) Proceed to 7.4.5 step 3, or return to Measurement mode by pressing the ∆ and ∇ keys
simultaneously (escape).
