Enhanced functions
This menu item contains a submenu with additional parameters.
You can access these parameters by pressing the SET button
briefly.
If the submenu is protected with an access code,"Cod1" flashes
in the display.
- Press the "Set" button and hold it pressed until the valid code
no. is shown.
- Then briefly press the "Mode/Enter" button.
Delivery by ifm electronic: no access restriction.
Display unit
The measured value and the values for SP1, rP1, ASP and AEP
can be displayed in the following units: mbAr, kPA, PSI.
Select the display unit before setting the switch points (SP1,
rP1) and the limits for the analogue output signal (ASP, AEP).
This avoids rounding errors generated internally during the con-
version of the units and enables exact setting of the values.
Setting at the factory: Uni = mbAr.
Display mode
2 settings can be selected:
• P = Pressure in the unit set in Uni.
• P% = percentage value (pressure in % of the set scaling of the
analogue output. The following applies: 0% = ASP value;
100% = AEP value).
NOTE: Display "0%" does not mean that the system is free of
pressure!
Analogue start point
Measured value at which 4 mA / 0 V is provided (20 mA / 10 V if
OU2 = InEG / UnEG).
ASP can also be set by means of the teaching process (→ tASP).
Analogue end point
Measured value at which 20 mA / 10 V is provided (4 mA / 0 V if
OU2 = InEG / UnEG).
Minimum distance between ASP and AEP = 25%
(turn down 1:4).
AEP can also be set by means of the teaching process (→ tAEP).
Setting range for ASP / AEP:
