Siemens SIRIUS 3RW55 - Page 223

In the test mode function "Test with small load", the motor operating states and all functions and
messages can be executed and displayed by the 3RW55 or 3RW55 Failsafe soft starter as in
normal operation.
If, during an active "Test with small load", the 3RW55 or 3RW55 Failsafe soft starter detects that
the main power current is missing, a fault is generated with a shutdown command and the
message text "Line voltage for test required". After connecting the 3RW55 or 3RW55 Failsafe soft
starter to the main supply this error message can be acknowledged with Reset.
The error monitoring functions that are to be attributed to a missing or inadequate main supply
are not active. The test mode function "Test with small load" remains active until the test mode
function is deactivated.
The motor and intrinsic device protection functions of the 3RW55 and 3RW55 Failsafe soft
starters remain active according to their parameterization and are not in󹪞uenced by the test
mode function "Test with small load".
Requirements
• The 3RW55 or 3RW55 Failsafe soft starter is connected to the main circuit.
• The test mode functions, e.g. "Simulation" or "Self-test (user-test)" are deactivated.
• The test motor is connected to the 3RW55 or 3RW55 Failsafe soft starter.
• Permissible power range of the test motor:
– < 10% of the rated power of the motor provided for the application
– ≥ 1 kW
• The test motor is switched o󹪜 prior to activation of the test mode function "Test with small
load".
• The 3RW55 or 3RW55 Failsafe soft starter must be in Test mode (Page 221). In test mode, the
"RN" LED 󹪞ashes green on the 3RW55 or 3RW55 Failsafe soft starter.
Note
Activating test mode
If you activate or deactivate "Test with small load" on the 3RW5 HMI High Feature, you will
automatically also switch to Test mode or Normal operation. For activation and deactivation
on the 3RW5 HMI High Feature, the 3RW5 HMI High Feature must have master control.
