7.2 Triggering devices – input signals
The triggering device can be a manual start button, a sensor on a conveyor line, a switch which
is automatically activated when a product is placed onto it, an external PLC built in a robot, a PLC
ultimately controlled by an ERP system, et cetera.

• C24V red (leftmost) and X1-1 and include a switch or relay in this circuit. This can be
done with any kind of switch or relay. By closing this circuit, you trigger the applicator to start a
print & apply cycle. If the AG3000 is controlled by an external system (e.g. an intermittent
product forwarding system) a controller in that system can close this circuit and trigger the
applicator.
• In case a PNP sensor is used you connect the sensor wires as follows: BROWN to +24V (leftmost
connector), BLUE to Ground (second connector from the left), BLACK to X1-1
7.3 Outgoing signals
X1-6/X1-7 and X1-8/X1-9 form relay controlled switches.
In case of an application time out or printer error, switch X1-6/X1-7 will be closed (ON). If the
AG3000T is ready for the next print & apply cycle switch X1-8/X1-9 will be closed (ON). See both
picture 1 on this page and picture 1 on the previous page for a visualization.
Hence, by creating an electrical circuit over X1-6/X1-7 which is connected to a controller (e.g. a
PLC) on the side of the auxiliary system, that system will know when there is an error and can be
programmed to react in any desirable way (e.g. stop forwarding products, start a warning light).
Hence, by creating an electrical circuit over X1-8/X1-9 which is connected to a controller (e.g. a
PLC) on the side of the auxiliary system, that system will know the next product can be labeled.
Such system can be programmed to react in any desirable way (e.g. placing the next product
under the applicator).
