Wavetronix Click 111 Using Manual page 11

Polarity
The next parameter the DIP switches can set is polarity. This is configured on the fourth DIP switch, labeled S4,
using switches 1–3 (S4:1–3).
Note. This parameter can also be changed using the front panel menu or Click Supervisor.
This parameter sets whether a call on an output channel is indicated by high voltage or low voltage. It can be set
for both the channel outputs and the master fault output. This setting does not affect how the LEDs on the front
panel work.

If switch 1 is on (flipped up), Hardware mode is selected, meaning that the data enable parameter will be
configured using the DIP switches, and Click Supervisor and the front panel menu will be able to display the
current setting, but not change it. If switch 1 is off (down), Software mode is selected and only Click Supervisor and
the front panel menu will be able to both display and change the current setting.
Warning. If you don't have switch 1 on (flipped up) to set it to Hardware mode, anything you set on switches 2 and
3 will be ignored by the Click 111.
Fault
The last parameter the DIP switches can set is fault settings. These are configured on the fourth DIP switch,
labeled S4, using switches 4–6 (S4:4–6).
Note. These parameters can also be changed using the front panel menu or Click Supervisor.
These switches configure two options for the fault function:
Global fault enable/disable for the entire card – If this switch is on, then no faults will be indicated.
■
Fault state: call or no call – This configures whether a fault produces a call or a no-call on output channels
■
whose bus has gone into failsafe. If this switch is off, then when a bus goes into fault, the channel outputs will be
represented by a call (which may be a high voltage or a low voltage depending on the card's polarity setting). If
this switch is on, then a bus fault will cause the corresponding channels to go into a no-call state.
