4. COMPONENT NAMES AND FUNCTIONS
4.1 Front Panel
FEED
ALARM
ACK
(Ack-key/Cursor Down-key)
The ‘ACK’-function is used to acknowledge alarms. Note that this function is only
effective if the alarm relay is in the hold-mode (see 5.3.7), and if the indicator status
is in the hold-mode (see 5.3.7). When you press this key in case an alarm occurs and
the ALM-indicator is flashing, the current alarm situation will be indicated and the
relay will be reset.
The function: The display is designed in an interactive way, which means that it
will ask you to enter the necessary data. In case there are several possibilities to
choose from (e.g. ON or OFF), use this key to show the previous choice.
(Feed-key/Move to Next Digit-key)
The ‘FEED’-function feeds the chart paper until this key is released (see also 5.3.2).
The function moves the cursor to the next digit while setting parameters. Please
note that there is not a back-space key provided. For that reason, the cursor moves
from the last digit to the first digit again (see 6.2).
(Ent-key)
The ‘ENT’-function allows you to keep the data you entered during the setting
procedure. Pressing ‘ENT’ results in moving to the next display in the same
(setting-) flow. Pressing ‘ENT’ after the ‘SET OK’-display appears, results in
starting the same (setting-) flow again.
3 Large sized VFD (Vacuum Fluorescent Display)
The display can show characters, bargraphs, and functions.
The backside of this display also illuminates the chart.
4 Chart and chart cassette
The recorder uses a Z-fold chart, 20 meter in length, with an effective analog trend
recording width of 180mm. The chart is stored inside a chart cassette.
5 IC Memory card slot (optional)
IC Memory cards are inserted into this slot for use.
6 Key-lock
The key supplied with the recorder should be removed from the key-hole to lock the
recorder. See 5.4. To use the key-lock, see 9.10.
