Device Functions

This section describes the functions of SICAM FPI.

Fault Detection

4.1.2
Phase Detection
Single Fault - In the L1, L2, L3 phase, if single fault is detected and the fault current persists for greater than
or equal to the set response time, the respective LED blinks to indicate a single fault (1 blink/s) and the phase
binary output contact changes its state from open contact to close contact.
Double Fault - The double fault condition is declared based on the following criteria:
•
A single-fault condition exists on any of the phase.
•
The fault current reaches to zero or less than the fault set limit in phase current sensor and persists for
more than 100 ms.
•
If it is followed by another fault that persists for greater than or equal to the set response time, the
respective LED blinks twice indicating a double fault (2 blinks/s).
Ground Detection
Fault - For ground E, the fault is detected when the fault current is greater than or equal to the set current
limit in the sensor and when the fault current persists for greater than the response time set in the device. The
Ground LED blinks to indicate a single-fault condition (1 blink/s). The ground binary output contact changes its
state from open contact to close contact.
Continuous Fault - If a continuous fault is present, the ground LED displays a double blink (2 blink/s) as long
as the fault persists. If there is no fault condition, the ground LED reverts to single blink.

DIP Switch

4.1.3
DIP switch is used for configuring the different parameter settings such as response time, auto-reset time, low-
battery status on binary output, and optical input test. By default, the DIP switch is in OFF position.
The DIP switch label is located on the rear side of the front fascia cover and indicates the configuration of DIP
switch.
The DIP switch settings can be viewed through the front fascia.

After changing the DIP switch setting, execute the functional check by pressing the push button for <3 s to
apply the changes.
A DIP switch is ON when it is positioned towards the top.
In factory settings, the DIP switch from DIP 1 to DIP 10 are set to zero position.
