Troubleshooting
This section provides the common problems of 7SR46 Argus relay and the recommended solution to resolve
the problem.
Observations Action
Relays will not communicate in a ring
network
•
Check that all relays are powered up with auxiliary power
supply.
•
Check that all relays have unique addresses.
•
In self-powered mode, check CT input current above
1.62 ⋅ I
smin
(1-phase) or 0.6 ⋅ I
smin
(3-phase).
Relay Does Not Power Up
•
Check whether correct auxiliary AC or DC voltage is applied,
and the polarity is correct.
•
Check whether phase connections are based on the terminal
diagram and if CT power is applied.
•
Check the USB port if the relay is connected with USB power
•
Check the battery healthy voltage if the relay is powered
with battery power.
Relay Does Not Accept The Password
•
The password entered is wrong. Enter the correct password.
•
If correct password is forgotten, note down the numeric
code displayed at the Change Password screen.
•
To retrieve the password, communicate this numeric code to
a Siemens customer care representative.
HEALTHY LED OFF/LCD Not Displaying
•
In the absence of auxiliary voltage, check the minimum
phase currents.
•
Check the error messages and the error codes under IRF in
the INSTRUMENT MODE.
Binary Inputs Do Not Work
•
Check that the correct BI voltage is applied, and that the
polarity is correct.
•
Check that the binary input settings such as the pick-up and
drop-off timers and the status inversion function are
correctly set.
External trip (ET) input does not work
•
Check whether the device is working on CT power or aux
power and ensure that the device is operating in healthy
condition.
•
Short the ET terminals with a resistance wire and ensure that
the line wire resistance is less than or equal to 20 Ω.
Low/Critical Battery Indication
•
Check whether paper strip between battery clip and battery
is removed.
•
Check whether battery is connected to the correct polarity.
•
Check the battery healthy voltage.
