
Time delays less than 10 cycles can be entered to the nearest 0.1 cycles through the HMI. All time
delays can be entered to the nearest 0.01 cycles from the ASCII command interface. Time delays entered
in cycles are converted to milliseconds or seconds. Increment precision after conversion is limited to that
appropriate for each of those units of measure.
Example 1. Make the following operating settings to the 62 element. Figure 4-60 illustrates these
settings.
Time units: ms
T1 Time: 100
T2 Time: 0
Retrieving General Purpose Logic Timers Status from the Relay
The status of each logic variable can be determined from the ASCII command interface by using the RG-
STAT (report general-status) or the RL (report logic) commands. Status can also be determined using
BESTCOMS
Metering screen. See Section 6, Reporting and Alarm Functions, General Status Reporting ,
for more information.
VOLTAGE TRANSFORMER FUSE LOSS DETECTION
60FL - Fuse Loss Detection
BE1-CDS240 relays have one 60FL element that can be used to detect fuse loss or loss of potential in a
three-phase system. The 60FL element is illustrated in Figure 4-61. When the element logic becomes
TRUE, the 60FL logic output becomes TRUE. A logic diagram is shown in Figure 4-62. Logic parameters
are shown in Table 4-34.

Trip Logic: 60FL Trip = (A * B * C * D * G) + (E * F * B * G) (See Table 4-42.)
Reset Logic: 60FL Reset = H * /K */L (See Table 4-42.)
