6.2.19 Use of the alarm contacts
The 4 alarm contacts of EXDTRX3 / EXDTRX324
receiver are associated with the first four preset
positions; as soon as the alarm is activated,
the positioning device and the lens adopt the
corresponding preset position; the last alarm
activated takes always priority. The EXDTRX3 /
EXDTRX324 can also receive an alarm command
even through theDCJ, DCT and DCTEL control
keyboard (which in turn receives it from the SM164B
and SM328B matrix); in such case the positioning
device and the lens move themselves into the preset
position n°1.
In order to use the alarm contacts it is necessary to
set the SW4 according to the following instructions:
• Dip 3 of SW4 set to the ON position: The alarm
contacts are activated;
• Dip 3 of SW4 set to the OFF position: The alarm
contacts are deactivated;
• Dip 4 of SW4 set to the ON position: The alarm
contacts are normally open;
• Dip 3 of SW4 set to the OFF position: The alarm
contacts are normally closed.
6.2.20 Operation mode of AUX4
• Switches: Dip 5 of SW4
Settings:
• Dip 5 of SW4 OFF: Normal operation;
• Dip 5 of SW4 ON: AUX4 is activated on alarm and
deactivated when the alarm signal stops.
6.2.21 Local keys for P&T motor
movement
The receiver has 4 local arrow-keys (on board) for
the P&T motor movement in the 4 directions (Up,
Down, Left, Right, Fig. 06, page 10). These keys are
very useful during P&T motor installation in order
to control the position of limit switches and/or the
right setting of the P&T motor. The arrow-keys have
total priority and, when pressed, they deactivate at
the moment the receiver remote use (by keyboards).
When the arrow-keys are released the receiver
functions are fully restored.
The combination of Up key and reset key is used to
carry out the auto-test ("6.2.18 Testing the receiver",
page 16).
