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
Test mode*
Leave the power circuits for the
actuators disconnected.
Safety mode**;
Individual system acceptance test
required
Prerequisite
Remarks
Check List
The plant and S5-115F are not
live, i.e. the main switch is turned
off.

Visual check of the installation,
observing VDE 0100 and
VDE 0113.
-
Test the program, block by block
-
Switch the PLC to ”RUN” mode.
Test mode*
Switch on power circuits of the
actuators
The PLC scans the program.
Test mode* / Stop
Insert the fuses for the sensors.
Leave the fuses for the actuators
and power circuits disconnected.
If the sensors function properly
and their signals are received, the
appropriate input LEDs must light
up on the I/O module.
Test mode* / Stop
Insert the fuses for the actuators.
Leave the power circuits of the
actuators disconnected.
- You can force each output using the
”FORCE VAR” programmer function.
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
- 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 mode* / STOP
- Switch the PLC to ”RUN” mode.
The PLC scans the program.
Individual system acceptance test by relevant authority, where applicable
- 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
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.
- 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).
Disconnect fuses for sensors and
actuators. Switch off the power
circuits of the actuators. Turn on
the main switch.
- Activate all sensors in sequence.
- You can interrogate each input using
the ”STATUS VAR” programmer
function.
