100 MM RECORDER USER GUIDE
3 OPERATION AND CONFIGURATION
3.1 OPERATION
The four-character, blue display shows the process value (PV) of each channel in turn, with each channel remaining
on display for 5 seconds. If 'Units' is selected 'yes' in 'Units configuration', the channel display units alternate with the
PV at the display. Current channel number is indicated by a green numeric character to the left of the PV display. Red
arrow heads to the right of the PV display indicate which (if either) of the displayed channel's alarms is active, and
whether the alarm is configured absolute high (up arrow) or absolute low (down arrow).
Operation of either the Enter or the Cancel key allows entry to the recorder's configuration menus, via a password.
The password is set to 010 at the factory, but can be edited in 'Instrument Configuration' (section 3.2.11).
Notes:
1.
Channels configured as 'Off' do not appear in the scroll sequence. If all channels are off, then channel 1 is shown
'Off' continuously.
2.
Unit string characters k, w and x cannot be displayed by a seven-segment display and are replaced by the special
symbol ' '. Similarly, the letter 'm' is displayed as 'n.n'. Because 'n.n' takes two character spaces, if an 'm' is used
in a unit string, the right-most character of four-character strings is lost. The above applies only to the display - the
characters are printed correctly on the chart.
3.
If the actual input value exceeds the configured range, +999.9 is displayed for over range; -999.9 for under range.
3.1.1 Channel Hold
Operation of the cursor key causes the currently displayed channel's value to remain permanently on display (Channel
hold). Channel hold is indicated by a red 'H' below the channel number. (This red 'H' symbol is also used to display
chart hold (pen park) mode.) To return to normal scroll mode, the cursor key is operated a second time.
3.1.2 Channel scroll (Manual)
The channels can be scrolled through in both normal and channel hold mode by operation of the scroll up/down keys.
In manual scroll all fitted channels are displayed when called, even if they are configured to be 'Off'.
3.1.3 Units display
See
section 4.4.1
instead, if the 'Channel Tags' option is fitted.
If 'Units' have been selected 'yes' in the top level configuration menu, then the PV and Units displays alternate, with
the PV being displayed for three and a half seconds, then the units string for a second and a half. See note 2 above for
un-displayable characters.
3.1.4 dFlt display
If the recorder's configuration should be found to be corrupt at power-up, a default configuration is loaded instead and
'dFlt' is displayed, as a warning to the user, until either the Cancel or Enter key is operated.
