During operation, 3 LEDs indicate the units’

operating status and the fault conditions.

The unit is ready for operation when:

● The “POWER” LED lights up

and

● The LEDs “CH.1” and “CH.2” are both lit

(high signal at the safety outputs)

● The LEDs “CH.1” and “CH.2” are both

out (low signal at the safety outputs).

LED CH.1 is assigned to safety output 14,

LED CH.2 to safety output 24.

INFORMATION

Supply interruptions lasting longer

than 20 ms are detected as an error.

The LEDs indicate an error and the

safety outputs carry a low signal. The

plant or machinery driven via the

safety outputs will be shut down. The

unit can only be restarted by

switching the supply voltage off and

then on again.

Error

Supply voltage is missing, too low, wrongly

connected

Unknown operating mode, initialisation phase, start

not executed

Error in the wiring of input circuit S11, S12, S21,

S22

1.) Feedback loop open on start-up

2.) Only one channel of the input circuit is open or

is partially operated

1.) Feedback loop open on start-up

2.) Only one channel of the input circuit is open or

is partially operated

3.) External feedback loop closed on start-up, but

internal feedback loop faulty

Simultaneity conditions not met

A pushbutton is defective or there is a wiring error

Error coding, see Table 3

Remedy

Apply supply voltage: A1 - +24 VDC and

A2 - 0 VDC

Permitted voltage range: 19.2 ... 30 VDC

Depending on operating mode: Press reset button

or perform start-up test

Rectify wiring error, restart unit

1.) Close feedback loop, open input circuit, start

unit again

2.) Open both input circuit channels

1.) Close feedback loop, open input circuit, start

unit again

2.) Open both input circuit channels

3.) No remedy available to user - send unit to Pilz

Release the two-hand button and press it again.

Change pushbutton or rectify wiring error

See Table 3

Table 1: Display of fault conditions

Errors

Fault conditions are indicated by flashing

the LEDs. Some errors are displayed

through periodic flashing (see Table 1); with

other errors it is possible to establish an

error code through the number of flashes

(Table 2).

These errors are always indicated by three

short flashes at LED CH.1 or CH.2. After a

longer pause, the LED will then flash at one

second intervals. The number of LED

flashes corresponds to a digit in the error

code. The error code can consist of up to 4

digits. The digits are separated by a longer

period without flashing. The entire sequence

is constantly repeated.

The error code can also be read into a PLC

via the diagnostic output. In this case the

error code will appear as a hexadecimal

sequence. The process of reading and

transferring data to a PLC is described in

the PLC Drivers manual.

INFORMATION

Leading zeros are not transmitted.

Error code 0: 16 flashes
