External Load Cell Supply

The internal load cell supply voltage of PR 5220 (V+, V-) is not connected.
The common line of the symmetrical external supply must be connected to the same terminal of PR 5220 as
the shield of the load cell/extension cable.

Specification of external supply: ±6 V DC +5 %, -30 %; max ripple. 50 mVpp; max. asymmetry ±3 %.

An external supply voltage smaller than 8 V DC (±4 V DC) must be set under

-[Weighingpoint]-[WP A]-

[Calibration]-[Param]-[External supply].

3.1.6.5

Connection via Intrinsically Safe Interface PR 1626/60

Connect the instrument to PR 1626/60 as described below. For additional connections, refer to the PR 1626/60
instrument manual. The internal load cell supply voltage of PR 5220 (V+, V-) is not connected.

Note:
If MX8 is closed in PR 1626/60,
[below 8 V DC] must be set under

-[Weighingpoint]-[WP A]-[Calibration]-

[Param]- [External supply].
