TX SIGNALS
The GROUND signal must be connected to clamp nr. 1.
The power supply signal OUT 0Vdc/P of module AL must be connected to clamp nr. 2. If the
AL1B or AL2B module is used, connect to OUT 0Vdc/P of AL module. If the ALdc module is
used, connect to OUT 0Vdc/P of the ALdc module. If the AL module is not used, connect
directly to the negative terminal of the power source which has to supply a +24Vdc voltage.
The power supply signal OUT 24V/P of module AL must be connected to clamp nr. 3. If the
AL1B or AL2B module is used, connect to OUT 24V/P of AL module. If the ALdc module is
used, connect to OUT 24V/P of the ALdc module. If the AL module is not used, connect
directly to the positive terminal of the power source which has to supply a +24Vdc voltage.
The IN SINC signal of AL module must be connected to clamp nr. 4. If the AL module is
used, connect to the signal SINC present on the module, otherwise connect to the signal
SINC directly on the RX module.
ALdc SIGNALS
The ALdc module includes, besides the clamps of the signals connected to TX and RX, the
two power supply signals IN 24Vdc, IN 0Vdc and the GROUND signal, two driven contact
relays excited by the signals OSSD A 24Vdc and OSSD B 24Vdc connected to the OSSD
outputs of RX.
Moreover, another terminal board is present, from which the NA contacts of the two relays
can be derived: OSSD A CR, OSSD B CR.
AL1 SIGNALS
Besides the clamps of the signals connected to TX and RX, the AL1B module houses even
another terminal board, which the two power supply IN 230Vac (or IN 24Vac) signals and
the GROUND signal must be connected to.
AL2 SIGNALS
Besides the clamps of the signals connected to TX and RX, the two power supply IN
230Vac (or IN 24Vac) signals and the GROUND signal, the AL2 module houses two force-
guided relays excited by the OSSD A 24Vcc and OSSD B 24Vcc signals connected to the
OSSD outputs of RX.
Moreover, another terminal board is present, from which the NA contacts of the two relays
OSSD A CR, OSSD B CR can be extracted.
Function of check of the support relay outputs at the OSSD solid state outputs
If support relays are used in output to the module are used, it is necessary that, at least at
the end of each cycle, the real switch of these relays to the rest state (NC contacts closed)
is checked. The opening of OSSD A-B OFF produces the intervention of the outputs of DSP
LASER, setting them just to state OFF. The DSP LASER device is not provided with a
feedback circuit for the control of the real switching of the support relays in output. This
function must be executed by the control circuit of the press. In order to be sure of the OFF
state of the outputs, the test signal must remain low for at least 100 msec.
Generation of the High speed closing signal
Other solutions are possible; however, they must be compatible as logic and must not
introduce a time delay, in the generation of the signal High speed in press brake closing (IN
AV), greater than the command of the high speed EV.
An example of circuit for the generation of the signal High speed in press brake closing (IN
AV) can be realized inserting one relay K1 with the coil in parallel to the solenoid of high
speed EV.
The NA contact of the relay will generate the signal High speed in press brake closing (IN
AV) necessary to DSP LASER.
