5.6 Encoder and Sync Switch Installation
Sync Switch Connection
- General Information
The sync switch should be connected to a digital input on the SCB board in the
control cabinet (non-ex connection) as described in the following.
The system has connections for 2 sync switches (non-ex connection only), where
switch 2 may be used in the rare cases when the robot works with ‘check point
functionality’ enabled. The following descriptions show connections for sync
switch 1.
Non-Ex Connection
A non-ex sync switch can be connected directly to a digital input in the control
cabinet according to one of the following alternatives:
Figure 44 Non-ex sync switch connection alternatives
If a ‘normal’ switch, photocell or initiator with a switch output is used, the switch
must be connected as shown in Alternative A.
If a switch with open-collector transistor output is used, the output from the switch
should be connected as shown in Alternative B (PNP) or Alternative C (NPN).
Ex Connection
An ex sync switch must be connected via a transformer isolated barrier to avoid
violating the explosion safety for the spray booth.
