Chapter 5 Programming
To set record rates use the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Record Rate” on the menu and press
ENTER. There are three options: “Autorate”, “Individual Rate”, and “All rates”.
5.7.6.1 Autorate
Autorate enables the record rate to be changed on an Alarm event. To enable auto rate change, use the UP
(
↑) or DOWN (↓) Arrow Keys to highlight “Autorate” and press ENTER. You will be presented with a display
that shows “autorate=NO” or “autorate=YES”. Press the YES or NO keys to enable or disable the autorate
change on alarm option then press ENTER to return to the record rate menu.
5.7.6.2 Individual Rates
To set the individual record rates per channel use the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Individual
Rate” and press ENTER. You will be presented with a point selection keypad that enables the selection of
the specific point to be programmed. Enter the point number and press ENTER. This brings up the record
rate entry keypad and a display that shows “secs(lo)
→XXX←” where XXX is the current sampling rate in
seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then
press ENTER to activate. The display will show “secs(hi)
→XXX←” where XXX is the current record rate in
seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then
press ENTER to activate and return to the Record Speed menu. Repeat the above procedure for each point
to be programmed. Press EXIT at any time to return without altering the setting and to return to the Record
Setup menu.
5.7.6.3 All Rates
To set the record rates for all channels at once, use the UP ( ↑) or DOWN (↓) Arrow Keys to highlight “All
Rates” and press ENTER. You will be presented with a display that shows “secs(lo)
→XXX←” where XXX is
the current record rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum
of 600 seconds, then press ENTER to activate. The display will show “secs(hi)
→XXX←” where XXX is the
current record rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of
600 seconds, then press ENTER to activate and return to the Record Rate Programming menu. Press EXIT
at any time to return without altering the setting and to return to the Record Setup menu.
NOTE: To set the record rate to 8 times per second, select 0 seconds.
NOTE: Although the record rates are shown as low and high, the “low” rate can in fact be faster than the
“high” rate. The low and high rates are defined by selection in the FUNC menu. If the digital I/O
option is fitted the switch inputs can be set to change record speed. An active input selects the
“high” speed, an inactive input selects the “low” speed. The current record rate (high or low) is
indicated in the Disk Status Window, the high rate being indicated by REC
↑↑↑↑↑ and the low rate
indicated by REC
↓↓↓↓↓. The inputs can be overridden by the FUNC menu until a change of input state
takes place. If you do not plan to use the change record rate option, set both record rates to the
same value.
The logic for external record rate change is as follows:
FUNC SWITCH RECORD RATE
high lo to hi high
high hi to lo low
low lo to hi high
low hi to lo low
