5.2 Connecting the process indicator
LWARNING
Danger! Electric voltage!
‣The entire connection of the device must take place while the device is de-energized.
5.2.1 Power supply connection
• Before wiring the device, ensure that the supply voltage corresponds to the specification
on the nameplate.
• For the 90 to 250 VAC version (mains connection), a switch marked as a circuit breaker,
as well as an overload protection device (rated power ≤ 10 A) must be fitted in the
supply line near the device (easy to reach).
• For version 20 to 35 VDC or 20 to 28 VAC: The device must be powered only by a power
unit that operates using a limited energy circuit in accordance with UL/EN/IEC 61010-1,
Section 9.4 and the requirements in Table 18.

6.3.3 Locking the configuration
User code
The configuration can be locked against unauthorized access by entering a four-digit code.
This code is defined in item 55 "Parameter/User Code". All the operating parameters
remain visible but can only be modified by first entering the user code. The "Key" symbol
appears on the display.
If the limit values are also to be locked, set the "Limit Code" to "On" in menu item 55. Limit
values can then only be changed after entering the user code. If the limit code is set to "Off",
limit values can be changed without entering the user code. All other parameters are
locked, however.
Hardware locking
Configuration can also be locked using a plug on the back of the device (→  13,  20).
This locking is indicated by a "padlock" symbol on the display. For hardware device locking,
set the jumper in the top right-hand corner on the back to position J1.
A0031364
 13 Position of the jumper on the back of the device
Hardware locking does not affect the PC operating software.
