Test - Siemens SIMOCODE pro System Manual

F.2.6

Test

SIMOCODE pro offers users the convenient option of checking the
complete motor protection chain (incl. actuators and sensors such as
contactors, thermistors). This can, for example, be used to carry out tests
according to IEC 60079-17.
This test includes a complete function test. For this purpose, all three test
phases are to be carried out (hardware test, current feedback, motor
protection tripping, see below). The test can be carried out using the "TEST/
RESET" buttons provided, or automatically via the bus. Due to existing self-
test routines, tripping currents do not need to be started in order to carry
out testing.
Test phases
• Phase 1: Hardware test/lamp test (0 to 2 s):
The hardware (e.g. the thermistor electronics) is tested, all LEDs and displays
are activated, including lamp controls. Contactor controls remain unchanged.
• Phase 2: Hardware test results (2 to 5 s):
If there is a fault, the "HW fault basic unit" fault is triggered.
If there is no fault:
– The "GEN. FAULT" LED flashes when no main current is flowing
– The "GEN. FAULT" LED flickers if main current is flowing in all three
phases (special case: for "1-phase load" in one phase).
• Phase 3: Relay test (> 5 s):
If testing is carried out with tripping, the contactor controls are deactivated.
The following table shows the test phases carried out when the "TEST/
RESET" button is pressed for the required length of time:
