8.4 Protection Simulation
NOTE
This function is protected by the security access code.
Software simulation functions let you test the soft starter's
operation and control circuits without connecting the soft
starter to mains voltage.
The MCD 500 can simulate each different protection, in
order to confirm that the soft starter is responding
correctly and reporting the situation on the display and
across the communication network.
To use the protection simulation:
1.
Open the Main Menu.
2.
Scroll to Protection Sim and press [OK].
3.
Use [
▲
] and [
▼
] to select the protection you want
to simulate.
4.
Press [OK] to simulate the selected protection.
5.
The protection message is displayed while [OK] is
pressed. The soft starter's response depends on
the Protection Action setting (parameter group
16).
6.
Press [Back] to return to the simulation list.
7.
Use [
▲
] or [
▼
] to select another simulation, or
press [Back] to return to the Main Menu.

NOTE
If the protection trips the soft starter, reset before
simulating another protection. If the protection action is
set to
Warn or Log
, no reset is required.
If the protection is set to
Warn & Log
, the warning
message can be viewed only while [OK] is pressed.
If the protection is set to
Log only
, nothing appears on the
screen but an entry will appear in the log.
8.5 Output Signal Simulation
NOTE
This function is protected by the security access code.
The LCP allows the user to simulate output signalling in
order to confirm that the output relays are operating
correctly.
NOTE
To test operation of the flags (motor temperature and low/
high current), set an output relay to the appropriate
function and monitor the relay's behaviour.
To use the output signal simulation:
1.
Open the Main Menu.
2.
Scroll to Output Signal Sim and press [OK], then
enter the access code.
3.
Use [
▲
] and [
▼
] to select a simulation, then press
[OK].
4.
Use [
▲
] and [
▼
] to turn the signal on and off. To
confirm correct operation, monitor the state of
the output.
5.
Press [Back] to return to the simulation list.

8.6 Digital I/O State
This screen shows the current status of the Digital I/O in
order.
The top line of the screen shows the start, stop, reset and
programmable input.
The bottom line of the screen shows programmable
outputs A, B and C.
The screen shot shows the stop input (17) as closed (1)
and the start, reset and Input A inputs (15, 25, 11) as open
(0). Relay A (13, 14) is closed and relays B and C (21, 22, 24
and 33, 34) are open.
