1. Description
The EIW-C18 serves as monitor for direct or alternating currents
in voltage power stations. It indicates an overrun or underrun of
the selected thresholds and releases a switching operation. In case
of an error the numeric displays indicate the cause of error. Ma-
nual settings on the device allow to select the current type to be
measured (AC or DC), one measuring range out of two (0.01 A to
1 A or 1 A to 15 A), an upper and a lower threshold, the response
delay (0.1 s to 9.9 s) and the error memory (on or off).
The two current measuring ranges (0.01 A to 1 A or 0.1 A to 15 A)
are selected by the contacts.
Errors can be acknowledged directly on the device and via an
external contact.
