100 MM RECORDER USER GUIDE
3.2.10 UNIT
This allows the user to choose whether or not to display the channel units or not. If 'No' is selected, the background
display carries out its normal 5-second scroll through the channels as described in section 3.1 above. If 'Yes' is se-
lected, then the normal 5-second scroll continues, but each channel's units are displayed for about a second and a half
just before the next channel's PV appears. See Note 2 in Section 3.1 regarding non-displayable characters.
3.2.11 INST
This section of the configuration allows the Password to be edited, the 'Common Relay' function to be enabled/disa-
bled, the chart cassette type to be defined (roll or z-fold (fanfold)), Alarm Hysteresis to be set, Alarm messages to be
enabled or disabled, an instrument descriptor to be entered and the operator access level to be defined.
Figure 3.2.11 Instrument configuration menu.
PASS
Allows a new password to be set for entry to the configuration menus. If set to '000', no password is required for sub-
sequent entry to configuration. See also 'Operator access' in section 3.2 above, and ACES below.
CREL
Common Relay enable. When set to 'On', Channel 1 Alarm 1 relay operates if any channel's alarm becomes active.
When set to 'Off', the relay operates only when channel 1 alarm 1 becomes active.
DESC
Allows a 20-character text string (descriptor) to be entered using the cursor and up and down arrows to enter each
character in turn. When the cursor is operated from the 20th character position, it returns to the 1st character position.
To indicate that this has happened, character 1 of the decriptor is always preceded by a special character ( ). For
example, were the descriptor '
DOWNLINE TEMPERA
TURE
' to be entered, (where the highlighted text indicates the
four characters on display) and the cursor operated from the final E, the display would change to : "
DO
NLINE
TEMPERATURE
'.
As indicated above, characters which cannot be displayed (K, M, W, X) are represented by another special character
( ). (These non-displayable characters do print correctly on the chart). See section 3.1 above for the full character
set available.
