number
OCBF-A 54
•
Press 4 (= Logic circuit) on the "Test" sub-menu screen to display the "Logic circuit" screen.
•
Enter a signal number 54 (OCBF-A) to be observed at monitoring jack A and press the
ENTER key.
•
Apply a test current, adjust the magnitude of the current applied and measure the values at
which the element operates and resets.
•
Check that the measured values are within 5% of the setting in operation and within 5% of the
setting

or vice versa.
OCD has a fixed setting of 0.5 A and 0.1 A for 5 A rating and 1 A rating respectively.
6.5.2 Timer
The pick-up delay time of the variable timer can be measured by connecting the monitoring jacks
A and B to a time counter as shown in Figure 6.5.2.1. Jacks A and B are used to observe the input
signal and output signal of the timer, respectively.
