Cryomagnetics Model 4G Operating Instruction Manual 25
Alarm HI and LO Limits
The output current is compared to these values and, if they are exceeded, alarm messages will
appear on the monitor display. If the optional alarm relays are installed, they will open upon an
alarm condition. If alarm messages are not desired, set these to a high value or to the maximum
capability of the module.
Alarm Relay Bypass
If the optional alarm outputs are installed and the user does not want them to open under any
condition, Alarm Relay Bypass should be set to ON. The outputs will remain closed as long as the
4G is powered on.
Alarm Relay Autoreset
There are two ways to reset alarms: automatically, when the current falls under the alarm limits, or
manually, by using soft keys provided on the display. Set Alarm Relay Autoreset to On to perform
the reset automatically.
