Figure 12 - Schematic of SIL 2 system wiring for fault detection in standby mode only

–

2 wire installation

To evaluate the total current drawn from the SIL 2 unit, use the equation below.

In standby mode, where there is no fault, RLY 1-1 is open. This means the voltage only passes through the customer EOL resistor and the current
drawn from the SIL 2 board is 25mA. Therefore, the equation for a No Fault scenario is then:

In standby mode, where there is a fault, the circuit is closed. This means the voltage passes through both the customer EOL resistor and current sense
resistor and the current drawn from the SIL 2 board is 20mA. The customer must first calculate the resistance of the two resistors in parallel before
applying the currents to the equation. The equation for a Fault scenario is then:

Table 5: Resistor combinations and the currents drawn when no faults and faults occur

If multiple SIL 2 alarm horn sounders are to be cabled in series the monitoring connections differ from that of a single alarm horn sounder. For more
information see manual D197-00-651-IS available from the E2S website.
