Many of the alarm conditions require that you define setpoints. This includes
all alarms for over, under, and phase unbalance alarm conditions. Other
alarm conditions such as digital input transitions and phase reversals do not
require setpoints. For those alarm conditions that require setpoints, you must
define the following information:
• Pickup Setpoint
• Pickup Delay (depending on the alarm group, you choose the time in
seconds, 100 ms increments, or cycles)
• Dropout Setpoint
• Dropout Delay (depending on the alarm group, you choose the time in
seconds, 100 ms increments, or cycles)
NOTE: Alarms with both Pickup and Dropout setpoints set to zero are invalid.
To understand how the circuit monitor handles setpoint-driven alarms, see
Figure 6–2 on page 86. Figure 6–1 shows what the actual alarm Log entries
for Figure 6–2 might look like, as displayed by
SMS.
NOTE: The software does not actually display the codes in parentheses—
EV1, EV2, Max1, Max2. These are references to the codes in Figure 6–2.
