SIREC D Display Recorder 7ND4000

Programming
4-48
NOTE
To set the record rate to 4 times a second
(once every 0.25 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
4.7.7 Disk Full Alarm. It is possible to set
a threshold to indicate when the disk is full. The
indication is via a pop-up window on the screen, or if
the relay option is fitted, via a contact closure. The
threshold limit may be set by you to any value
between 1 and 100 percent. To set the disk full
alarm value perform the following:
NOTE
Setting the limit to 100% prevents the disk
full alarm from activating.
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
highlight the “Disk Full Alarm” option and press
ENTER. There are two menu options
• Setpoint
• Contact #.
A. Disk Full Setpoint - To change the disk full
alarm threshold:
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
highlight the “Disk Full Alarm” option and press
ENTER. Select “Setpoint” and press ENTER.
2. Use the alphanumeric keypad to enter the percentage
point at which the disk will indicate nearly
full (1 to 100 percent) and press ENTER.
B. Disk Full Alarm Output - To set the Disk
Full Alarm Output:
1. Use the UP (↑) or DOWN (↓) Arrow Keys to
highlight the “Contact #” option and press ENTER.
2. Use the keypad to select a relay contact number,
1 through 6, or 0 for no contact closure. Press
ENTER to return to the Record Setup menu.
NOTE
If the relay output option is fitted, the contact
selected above will close when the disk full
threshold is reached. Once a contact has
been selected, all disk errors (e.g.
Read/write, File not found etc.) will also
cause the same contact to close.
