transmitter: AKAS®-3P...: plug-in connector with PG 9 as strain relief
receiver: integrated plug-in connector with M 32 as strain relief

Cables to be laid separately from high-voltage cables. The cable laying must be arranged in a way that no
mechanical damage of the cable is possible. For that reason the cable must be installed in a reinforced hose if
not protected by the machine.
OSSD 1 and 2: Fail-Safe PNP outputs , max. 0,5A, with short-cut and side-current monitoring.
Output current for resistance u. Inductive loads in the on state = min. 0mA, max. 0.5 A, max.
Output current in the inactive = 50 uA max. Voltage in the inactive = 0.9V,
max. capacitive load = 200 nF, max. Cable resistance between OSSD and load = 10 Ohm
RXOK1 and 2: PNP-outputs with short-cut and side-current monitoring during switching on, max. 0,5 A
SGA , HUSP, SEU2K, KAST (KAST: only when using the external muting lamp): PNP-outputs max. 0,5A

time windows for the input
signals (basic tolerances)
1,5 ms between the interruption of a light beam and the disabling of the OSSDs
10 ms between the release of the foot pedal orthe opening of a protective circuit and the disabling of the OSSDs
10 ms between the opering of a protective circuit and disabling of the release of the rear stoppers RXOK1 & -2
2,6 ms between the opeing of the overrun traverse cam switch and the disabling of the OSSDs during the over-
run traverse test
switch-over from stopped state into closing state after enabling of the OSSDs : 300 ms (only with operatiing mo-
de with contactor/valve control EDM).
switch-over into slow speed state when the start is carried out within the range of the safety point (at SP = 1):
100 ms after detection of the closing movement state by the EDM, i.e. 100 ms after enabling of the OSSDs
when the press is operating without the EDM.
switch-over into fast speed when the start of the press is outside the range of the safety point (at SP = 0): 100
ms after detection of the closing movement state by the EDM, i.e. 100 ms after enabling of the OSSDs when the
press is operating without the EDM.
switch-over into slow speed state when the start of the press with slow speed request (200 ms after SGA = 0
has been transmitted to NC): 70 ms after detection of the the closing movement state by the EDM, i.e. 70 ms
after enabling of the OSSDs when the press is operating without the EDM.

Caution!!! Only if the accident preventing light barrier AKAS® has been installed according to the operating in-
structions and connected according to the wiring diagrams, and if all relevant national and international accident
prevention/safety regulations are observed , a safe operation is ensured !
Any modification of the specified circuits can cause hazardous states and is therefore forbidden.
Caution!! The use of both AKAS® ...without F series and the AKAS®...with F series adjusted to "operation with
connection to an additional safety PLC" receiver is only permitted in combination with an additional safety PLC
(e.g. FPSC) which provides the safe fast speed-/slow speed signals and closing request signals via cables with
short-cut and side-currant monitoring and which provides a safe processing of the OSSD-Signals of the AKAS®.
If the press does not posssess any position-monitored contactors for the switch-over from fast speed into slow speed,
a safe integration is possible using the Fiessler AMS-System.
