7 Switching Amongst Tariffs
Hardware Controlled
Tariff inputs Ta and Tb are each connected with refer-
ence to Tn.
Level 0: < 12 V
Level 1: > 45 V (max. 265 V permissible!)
Software Controlled (not included in MID scope of approval)
In the case of meters with bus (featureW1 … W7), four
further tariffs can be selected (software controlled).
8 Overview of Bus Systems
–
LON-Bus (feature W1)
– M-Bus (feature W2)
– Modbus TCP (feature W4)
– Modbus RTU (feature W7)
Interface descriptions for energy meters with bus connection
can be found on the Internet at www.gossenmetrawatt.com.
9 Error Messages – Reset
Display
If an error occurs, the respective error code and active
energy or instantaneous power are displayed alter-
nately.
LOVoLt error
In case of LOVoLt error (phase voltages too low), back-
ground illumination, and if applicable the bus connec-
tion, are deactivated. The load profile (featureZ1) cannot
be viewed as long as the error is pending.
10 Repair and Recalibration
Note for Test Laboratories
Direct measuring meter: Testing is only possible with
source which supply currents superimposed on volt-
ages.
Calibration Display
Display of energy values with increased resolution can
be selected for testing or calibration purposes.
➭ Press and hold the ENTER key once to this end. The
firmware version is displayed with a red back-
ground.
➭ Press the UP key twice. The calibration display ap-
pears with a pink background.
See section 6.2 with regard to resolution depending on
type and feature.
Recalibration can be conducted at any time by our fed-
erally approved test laboratory (EB-8) (see repair and
service address on the back of the folder).
Calibration capability is valid for 8 years in Germany.
11 Manufacturer’s Guarantee
The energy meters are guaranteed for a period of 3
years after shipment. The manufacturer’s guarantee
covers materials and workmanship. Damages resulting
from use for any other than the intended purpose or
operating errors, as well as any and all consequential
damages, are excluded.
