ABB 81943A041-1 Input/Output Module

The recording period depends on the number of samples. The recorder

can be set with the pre-trigger to record event data even before the

event happens.

Stopping the recorder can be triggered by either an event or a preset

time. For easier management and trouble-shooting, event data can be

transferred and analyzed. The data transfer is made by a link through a

plug on the front panel of the SYMAP® device.

Diagnostics and monitoring

SYMAP® provides various diagnostic and monitoring functions:

•  all memories (ROMs, RAMs, EEPROMs)

•  all analog reference voltages

•  automated test sequences

•  control power ON/OFF

•  binary input and output for control logic

The following supervising systems are offered by SYMAP®:

•  self-diagnostics

•  inputs of analog data (auxiliary circuit)

•  status and position of switching device and motor’s on-off status

•  supervising supply of trip coil

•  gas pressure

• temperature inside panel

•  each operating life of breaker (hours)

• 32 analog / temperature inputs, channel-wise configurability in 2-conductor switch

• 16 temperature inputs in 3/4-conductor switch
