“Set Output Alarm Limits” Menu
The current process value for each channel is shown
along with the current low and high setpoints. The
top row shows the high “H” setpoint with a white
background while the bottom shows the low “L”
setpoint with a grey background. The current
process value is shown in yellow on a green
background. If the low or high alarm is active this is
displayed in red below the high or low relay
designation for the given channel.
To change the high or low scaling limit simply click
on the value that you wish to change and enter the
new value to be used.
For each relay there exists an adjustable delay time.
The units for this delay time settings are 0.1 seconds.
For the setting of 50 for the delay time this is 5.0
seconds. The time delay setting is the ONLY setting
that is NOT stored in retentive memory. This means
that it must be re-entered in the case that the unit is
powered down. All other settings are maintained in
the even of a power loss since they are stored in
retentive register.
