Setting the switching points
The PE2 is in the programming mode:
1. Press to show the SP1 menu item.
2. Press to be able to set the switching point SP1.
3. Set the desired switching point using
The following applies: | RPx | < | SPx |, | SPx ≠ 0 at 0-16 bar|, |FLx < FHx|
If SPx/FHx is adjusted and this adjustment causes SPx < RPx or FHx<FLx, then RPx or FLx is
automatically set to the smallest value possible.
During adjustment, the adjustment of SPx or FHx is decisive:
W
If SPx/FHx > 0 bar, then RPx/FLx = 0% FS to SP -0.5% FS
W
If SPx/FHx < 0 bar, then RPx/FLx = SP + 0.5% FS to 100% FS
4. Confirm the set value by pressing
The display returns to the menu level.
5. Repeat steps 1 to 4 to set the resetting point RP1, switching point SP2 and resetting point
RP2, one after the other.
After you have entered the last switching point, you can go back to display mode by
simultaneously pressing and , or select the EF menu and press
extended programming functions.
Configuring the switched output
The PE2 is in the EF extended programming functions.
Setting the switch-on and reset delay
1. Select menu item DS1 or DR1 and press
2. Set the desired switch-on or reset delay with
3. Press to accept the selected value.
4. Select menu item DS2 or DR2 and press
5. Repeat steps 2 and 3.
Setting the switching element function
1. Select the menu item OU1, OU2, or OUA.
2. Press to enable selecting the switching element function.
3. Select the desired switching element function with the
4. Press to accept the selected switching element function.
Using the password function
You can protect the PE2 from unintended access by entering a password. If a password has been
assigned, settings can only be changed if the password is entered.
The password 2677 is set as the master password.
Assigning a new password or changing a password
The PE2 is in the EF extended programming functions.
1. Press to show the PASS menu item.
2. Press to switch to the password activation.
3. Press and select YES.
4. Press to activate password protection.
The display switches to the password entry screen.
5. With and , select a four-digit password.
6. Confirm the set password by pressing
The display then returns to the menu level.
Password protection becomes active when you leave the programming mode or when no entry
is made within 10 s.
With NO, you turn off the password function.
Deactivating password protection
1. Press .
A prompt indicates that protection mode is activated.
2. Press to enter the password.
The display switches to the password entry screen.
3. Enter and , the password, or the master password, and confirm you entry with
If you have entered the correct password or master password, the display switches to the
password deactivation screen.
4. Press and select YES.
5. Confirm the deactivation by pressing
Programming mode is exited automatically.
Resetting previously set parameters
The PE2 is in the EF extended programming functions.
1. Select the RES menu item and press
2. Select the YES setting with the
3. Press the button to confirm the selection.
All parameters now reflect the factory settings.

Disassembly and Exchange

System is under high pressure!
Danger of injury and system damage from uncontrolled system operating states.
O
Make sure that the system component the PE2 is installed in is not under pressure or
voltage before beginning disassembly.
1. Make sure that the system is not under voltage or pressure.
2. Loosen and remove all connections.
3. Loosen the pressure switch from the (threaded) pressure connection using a wrench, or pull
the PE2 straight out of the push-in fitting.
4. Dispose of the packaging and used parts in accordance with the regulations of the country
where used.

Error and Warning Messages

The following error and warning messages may appear in the display of your PE2.
Display Cause
OL Applied pressure > end of measuring range
1)
OVERPRESS
UL Applied pressure < start of the measuring
1)
UNDERPRESS range
ERR3 Supply voltage > 32 V DC
2)
OVERVOLTG
ERR3 Supply voltage < 15 V DC
2)
LOW VOLTG
ATT2 During zero point adjustment, the applied
ADJ>LIMIT pressure is outside the permissible limit
(Selecting the extended programming
functions: ZERO).
LOCK The password function is active and an
KEYLOCKED attempt is made to go into the programming
mode.
1) There is an overshoot tolerance before the error message is output:
W
Measurement range 0 to 16 bar: -0.45 to16.45 bar
W
Measurement range -1 to +1 bar: (-1 to +1.05 bar)
2) NOTICE
W
> 40 V DC: (continuous): Damage to the electronics
W
< 15 V DC: An error message appears on the display, PNP outputs are switched off in a
defined manner and any existing analog outputs are set to 3.6 mA.
W
< 10 V DC: The display darkens. An error message appears on the display, PNP outputs are
switched off in a defined manner while analog outputs continue to function at 3.6 mA..
W
< 8 V DC: The minimum supply for the controller is not ensured; the controller switches off.
