3.3 ALARM SETTINGS
There are two possible alarm set point values for each of the two possible inputs/pens. They will be displayed only if the alarm
options are present and configured. The types of alarms and the ability to make alarm set point changes, is defined during
configuration. See Section 4 to select the types of alarms and to allow/disable alarm changes.
TO REVIEW/MODIFY ALARM SETTINGS
Repeatedly depress the SCROLL key. If any alarms exist, the alarm LED (ALRM 1/1, ALRM 1/2, etc.) for the first existing
alarm will flash along with its current alarm set point in the order shown below. Note that CC (for chart changing) will also
appear in the sequence when the SCROLL key is repeatedly depressed.
OUT 1/1 LED flashes Display shows Pen 1/Alarm 1 setpoint value
OUT 1/2 LED flashes Display shows Pen 1/Alarm 2 setpoint value
OUT 2/1 LED flashes Display shows Pen 2/Alarm 1 setpoint value
OUT 2/2 LED flashes Display shows Pen 2/Alarm 2 setpoint value
If Alarm Changes are allowed/enabled, use the UP/DOWN keys to change the setting. All alarm settings are defaulted to 0
and are adjustable from -9999 to 9999 (assuming no decimal positions).
If Alarm Changes are disabled, the settings cannot be changed, only viewed.
3.4 HIGH/LOW LIMITS
High or Low Limits are latching alarms. Once an alarm is engaged, it will remain active until BOTH of the following occur:
1) The alarm condition no longer exists (i.e. for a high limit the process value has fallen below the alarm
setpoint), and,
2) The alarm condition is acknowledged by depressing the red reset button to right of the display, on the platen.
The button will reset any limit alarms that can be reset.
If power is cycled and the alarm condition no longer exists, the corresponding limit will be reset.
Section 4 - Recorder Setup, Test, and Calibration
Because the MODE switch protects the configuration as well as the calibration of the recorder, "calibration seal" labels are
provided to cover up the switch, if desired, to secure the configuration and calibration, as well as record the date of the
calibration. The label looks like this:
If necessary, remove the label or "seal" to access the MODE switch.
The instrument has two basic "modes" of operation. The Run mode (as addressed in Section 3) is the normal operating
mode. The other basic mode is the Program/Test/Calibration mode, which is used only for setup, troubleshooting, and
calibration. The Program/Test/Calibration mode, accessed by having the MODE switch in the PROG/TEST/CAL position, is
further divided into the three respective modes of Program, Test, and Calibration. Each of these modes is divided into
sections corresponding to a portion of the programming parameters, or individual test or calibration functions.
The availability of various options (i.e. alarms, communications, etc.), as defined by the model number shown by the recorder
on power-up, will determine the selections offered in the Program, Test, and Cal mode. For example, if no alarm options exist,
then the alarm types do not need to be configured.
Located on the back of the access panel (inside the recorder) is a Short Form Programming Card that can be used as a
reference for selecting all program parameters.
