Functional Error; Optical Impulse Output; Data Interface - VOLTCRAFT VSM-105-60 Bedienungsanleitung

8. FUNCTION ERROR
The "VSM-105" is equipped with error recognition to monitor for functional errors. If one of the following errors is recognised, the internal
power register is "frozen" on the current state. The exclamation mark flashes, the error codes are indicated in the display and cannot be deleted
(example: "FF002"). The meter must be uninstalled.
For the two-directional meter, the power values for the two registers are displayed alternatingly.
Display Error description
FF001 Hardware error
FF002 Parameter error
FF003 Energy storage (EEPROM) defective

9. OPTICAL IMPULSE OUTPUT

The VSM-105 has an optical test output pursuant to EN50470-1 (impulse output). The pulse constant is 10,000 impulses/kWh at an impulse
length of 2 ms. The red LED does not output any further signal states and is inactive below the start-up threshold.

10. DATA INTERFACE

The meter's data interface is an optical (infrared) communication interface (D0).
The following measured values are output:
• The meter state Etot (15-digit in kWh, with 8 pre- and 7 post-decimal digits)
• The phase outputs PL1, PL2, PL3 (7
1
• The sum output Ptot (7 / -digit in W, 2 decimal digits, prefix)
2
The protocol is designed pursuant to EN62056-21 and EN62056-61.
The meter unidirectionally sends a dataset every two seconds.
