S5-115F Manual
4.3.2
Checking a Plant or Controlled System before Startup
Perform each step in the operator procedure shown in Table 4-2 before switching on the power
supply.
Table 4-2. Operator Procedure Prior to Switching On the Power Supply
Prerequisite
The plant and S5-115F are not
live, i.e. the main switch is turned
off.
Disconnect fuses for sensors and
actuators. Switch off the power
circuits of the actuators. Turn on
the main switch.
Test mode* / Stop
Insert the fuses for the sensors.
Leave the fuses for the actuators
and power circuits disconnected.
Test mode* / Stop
Insert the fuses for the actuators.
Leave the power circuits of the
actuators disconnected.
Test mode*
Leave the power circuits for the
actuators disconnected.
Test mode* / STOP
Test mode*
Switch on power circuits of the
actuators
Safety mode**;
Individual system acceptance test
required
Individual system acceptance test by relevant authority, where applicable
*
Control program and configuration data in RAM
** Control program and configuration data in EPROM/EEPROM
EWA 4NEB 811 6148-02
Check List
- Check the line voltage connections.
Protective ground conductorss must be
connected.
- Make sure that all modules plugged in
are screwed tightly to the mounting
rack.
- Compare the configuration of the I/O
modules to the location diagram. (Pay
particular attention to fixed and
variable addressing).
- For I/O modules, make sure that no
high-voltage lines (e.g. 220 V AC)
terminate at low-voltage connectors
(e.g. 24 V DC).
- Plug RAM user submodules required
into subunit A and B
- Enter subunit identifier in subunit A
using the programmer
( Vol. 2, chap. 1)
- Perform Overall Reset on S5-115
- Activate all sensors in sequence.
- You can interrogate each input using
the "STATUS VAR" programmer
function.
- You can force each output using the
"FORCE VAR" programmer function.
- Switch PC to Stop. Transfer all
configuration DBs to subunit A using
COM 115F
- Switch both subunits to RUN thus
triggering comparison of configured
I/Os with actual I/Os
Remarks: The green LED will light up if
there is no discrepancy
-
Test the program, block by block
-
Switch the PLC to "RUN" mode.
- Switch the PLC to "RUN" mode.
System Startup
Remarks
Visual check of the installation,
observing VDE 0100 and
VDE 0113.
After the power switch is turned
on, the green LEDs light up on the
power supply and the red "ST"
LED lights up on the CPU.
If the sensors function properly
and their signals are received, the
appropriate input LEDs must light
up on the I/O module.
The LEDs of the forced outputs
must light up and the circuit
states of the corresponding
actuators must change.
Block input via subunit A only
possible in PLC Stop mode
The PLC scans the program.
The PLC scans the program.
