8. ACCESSORIES
8.1 Scale card
The BA405C has a window below the control knob
to accommodate a scale card. Set point stations
can be supplied with a printed scale card showing
any units specified at the time of ordering e.g.
o
C,
mBar, RPM. If a printed scale card is not
requested, a blank card will be supplied.
Scale cards can easily be marked on site as
follows:
a. Remove the rear terminal block(s) and the
rear panel as shown in Fig 8.
b. Remove the end cap from the front panel
control knob using a thin bladed screwdriver.
This will reveal a screw collet which secures
the control knob to the shaft. Loosen the
collet by turning the brass split screwhead anti
clockwise and then carefully pull the control
knob from the shaft.
c. Pull the electronic assembly from the rear of
the enclosure.
d. Remove the blank scale card(s) and mark
with the required legend. Replace scale
card(s) taking care to align them within the
front panel window.
e. Slide the electronic assembly into the rear of
the enclosure and carefully guide the control
shaft through the front panel seal. Replace
the rear panel and terminals.
f. Replace the control knob and tighten the
collet screw. Finally push the knob end cap
into place.
8.2 Tag strip
The BA405C can be supplied with a thermally
printed tag strip on the rear panel. This tag strip is
not visible from the front of the instrument after
installation.
