Operation
1.8.0 1 = all-phase active power in positive direction
8 = cumulative value (meter reading)
0 = total energy (no tariffs)
0.9.1 Local time
Up display button
Down display button
The display is controlled using the Up and Down display buttons.
A short press of either button (< 2 seconds):
• Changes the Operating Display to Display Check
• Opens the Display Menu from the Display Check
• Runs sequentially through menus from item to item, and in lists from
value to value (either forwards or backwards).
A long press of either button (> 2 seconds):
• Opens a selected sub-menu
• Returns to the next higher level when End is displayed
• Browses through lists from main value to main value (either forwards or
backwards).
Simultaneously pressing both buttons cancels the function in use and
returns to the Operating Display.
The optical interface enables:
• Read out of meter data
• Parameter setting using MAP 120 Service Tool.
These functions are performed via a magnetically attached optical reading
head, e.g. FDC1.3.
The optical interface also functions as an optical switch. A light beam, e.g.
from a torch, has the same function as the Down display button. This
enables reading to be made from a distance, e.g. through a protective
glass screen in front of the meter.
The two green optical test outputs, one for active energy (right) and one
for reactive energy (left) are used to test the meter. They transmit
pulses corresponding to the power applied.
In a no load state, when no current is flowing, the optical test outputs are
continuously illuminated.
