The Service unit for Siemens audio frequency track circuits and axle counters SICO 2056 PEGA (V25591-Z1-A43) is suitable for
- Adjustments,
- Inspection, and
- Acceptance tests
on audio frequency track circuits of the following types:
- FTGS 46,
- FTGS 917,
- GLS 9/15, and
as well as on axle counters of the following types
- ZP43 E/M and
- ZP70 E/M.

The connection to the counting points is realized by the corresponding counting point adapters.

It replaces the former Tester V25921-Z1-A19 (PEGA 1211).

Automatic inspection of axle counters:
The measurement on axle counters can also be realized automatically. The measured values are listed fast and without any errors. SICO 2056 PEGA realizes all required measurements for the chosen axle counter and compares the measuring results with the limit values stored in the device. In case a measuring result exceeds the limit values, the automatic mode is interrupted and the measuring result is displayed accompanied by a note.

Storing the measured results:
At the end of the automatic measuring mode at the axle counter all measured values can be stored in a protocol in the FLASH memory.

Data entry on PC:
Prior to axle counter measurements the files with the axle counter names can be entered on a computer and afterwards transferred to the SICO 2056 PEGA with the data cable USB.

Recording mode for measuring results:
Measuring results can be stored automatically in a scheduled period in defined intervals.

Used as multimeter to measure:
- Voltage AC (mains alternating voltage),
- Voltage DC (direct voltage) or
- Frequency

Selective and broad-band alternating voltage and direct voltage measurements

High selectivity against interfering signals

Displays immediately the measured result

Menu operated

Large, excellent illuminated display
