5.7.7 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 the user to any
value between 1 and 100 percent.
NOTE: Setting the limit to 100% prevents the disk full alarm from activating.
To set the disk full alarm value use the UP (
↑) or DOWN (↓) Arrow Keys to highlight the “Disk Full Alarm” option
and press ENTER. There are three menu options: “Setpoint”, “Contact #”, and “Rec. contact#”.

keypad to select a relay contact number, 1 through 6, or 0 for no contact closure. Press ENTER to return
to the Data Recorder menu.
NOTE: If the relay output option is installed, 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.
5.7.7.3 Record Mode Alarm Output
It is possible to monitor the record mode via a contact closure. When the record mode is on, it closes the
selected contact. When the record mode is off, the selected contact is open.

closure. Press ENTER to return to the Disk Full Alarm menu. Then, press EXIT to get back to the Record
Setup Menu.
5.7.8 Format Disk
The floppy/zip disk or PCMCIA card must first be formatted before being used. This can be done in the unit, or
on any IBM compatible PC running MSDOS. The disks are formatted in MSDOS compatible format. Note that
only 1.44 Meg (High Density) 3½ inch floppy disks can be used.
To format a disk, first ensure the disk is not write protected, (the write protect slide must expose the hole in the
floppy disk). Open the door flap on the lower front panel to expose the drive. Insert the floppy disk, label side up
with the metal toward the drive opening. Insure the disk is pushed fully into the drive - it will be pulled in and
down.
Use the UP ( ↑) or DOWN (↓) Arrow Keys to highlight the “Format Disk” menu choice and press ENTER. You
will be presented with a display window that shows “format=NO*”. Press YES and then ENTER to start formatting.
You will be returned to the Record Setup Programming menu. The light on the disk drive will come on and the
disk will be formatted. The disk status window will indicate FORMAT while the disk is formatting. Once formatting
has been completed a window will pop up to announce “Format Complete” or it will indicate any error if the disk
could not be formatted. Press the “OK?” button to accept.
