ACCESSORIES

4.1

Display backlight

The BA577E-SS Timer or Clock can be supplied with
a   factory   fitted   backlight   that   produces   green
illumination enhancing display contrast and enabling
the   display   to   be   read   at   night   or   in   poor   lighting
conditions.   The backlight is internally powered from
the instrument power supply so no additional wiring
is   required,   but   the   supply   current   increases   as
shown below.

4.2       Control outputs

Although the dual isolated control outputs are factory
fitted options, they are described in the main body of
this instruction manual as they will be used for the
majority of applications, see section 2.4.   If control
outputs are required they should be specified when
the instrument is ordered.

4.3

Scale card

The   BA577E-SS   has   a   window   on   the   right   hand
side   of   the   display   through   which   a   scale   card
showing   the   units   of   time   such   as   hours   can   be
seen.   New instruments are fitted with a scale card
showing   the   units   of   measurement   specified   when
the   instrument   was   ordered,   if   the   units   are   not
specified a blank scale card will be fitted.   A pack of
scale   cards   pre-printed   with   common   units   of
measurement is available as an accessory.   These
can   easily   be   fitted   on-site   without   opening   the
instrument enclosure or removing it from the panel.
See section 3.5 of this instruction manual.

Custom   scale   cards   for   applications   requiring   less
common units of measurement are also available.

4.4

Tag information

New instruments can be supplied with a tag number
or application information printed onto the rear panel
adjacent   to   the   terminals.     This   information   is   not
visible   from   the   front   of   the   instrument   after
installation.

4.5

Rear cover sealing kit

The   BA577E-SS   Timer   or   Clock’s   rear   of   panel
ingress   protection   can   be   increased   from   IP20   to
IP66   with   a   BA495   rear   cover   sealing   kit.
Manufactured   from   316   stainless   steel   the   cover
incorporates two M20 unthreaded entries for cable
glands.   It allows the BA577E-SS Timer or Clock to
be installed in an open panel, or to provide additional
rear protection when installed within an enclosure.
