Power Status Indicators
The 5380 controllers use power status indicators show the status of MOD
power and SA power.
MOD Power Indicator
Table 2 2 describes the MOD Power indicator on a 5380 controller.
SA Power Indicator
Table 2 3 describes the SA Power indicator on a 5380 controller.
Table 22 - MOD Power Indicator
State Description
Off Module Power is not present
Steady green Module Power is present
(1)
(1) Although unlikely, it is possible that there is enough Module Power present for the indicator to turn steady green but the power
is not valid. Valid power is 18…32V DC to operate a 5380 system. If the system does not power up and operate successfully,
Module Power can be invalid.
If Module Power is invalid, we recommend that you make sure that the external power supply is working correctly, properly sized
for your application and that all wiring is correct.
Table 23 - SA Power Indicator
State Description
Off One of the following:
• Sensor Actuator Power is not present
• Status of Sensor Actuator power is unknown
Steady green Sensor Actuator Power is present
(1)
(1) Although unlikely, it is possible that there is enough Sensor/Actuator Power present for the indicator to turn steady green but
the power is not valid. Valid power is 18…32V DC in applications that require DC voltage and 18…240V AC in applications that
require AC voltage.
If Sensor/Actuator Power is invalid, we recommend that you make sure that the external power supply is working correctly,
properly sized for your application and that all wiring is correct.
