Configuring the Alarm Parameters
The FMS-1650 allows the user to specify multiple alarm setpoints for
each analog input. The Alarm Limits option on the Controller Setup
menus allows the high and low alarm setpoints to be configured as
required by the specific application. Selecting this option while the
unit is in positive isolation mode invokes the Pos ISO High Alarm SP
configuration screen shown in Figure 15. If the unit is in negative
isolation mode, selecting the Alarm Limits option invokes the Neg
ISO High Alarm SP configuration screen shown in Figure 18. If the
unit is in neutral isolation mode, then the alarm setpoints cannot be
configured, and the warning message shown in Figure 17 is displayed.
After entering the high alarm setpoint, the user is subsequently
prompted for the high warning setpoint, low warning setpoint, and
low alarm setpoint. These four setpoint values must be sequentially
decreasing or increasing in magnitude to be valid, depending on the
selected isolation mode.
Setting up the Alarm Buzzer
The FMS-1650 alarm resources provide support for both visual and
audible alerts. The Audible Alert option on the Controller Setup menus
allows the alarm buzzer settings to be configured. Selecting this
