assemblies may be ordered with or without indicators.
When ordered with an indicator, the assembly model code
includes a letter symbol for the indicator, such as B,
C, or D. When ordered separately, an indicator has its
own model code. See brochure
for details.
A
type B or BM visual indicator is suitable when only a
local warning is required. When it is necessary to signal
a remote warning device, control panel, or PLC, one of
the electric switches should be specified. Various kinds
of switches are available to provide a range of electrical
configurations, contact ratings, and connections.
The
D indicator incorporates a switch and built-in light for
both local and remote warning signals.
