SAFETY DEVICES
The Thalia board provides one
STOP
command input, and
two programmable obstruction sensing device inputs,
SAFE1
and
SAFE2
. All 3 safety inputs are
N.C. (normally closed)
contacts. Both SAFE 1 and 2 have a device supervision
circuit labeled
FAULT
. Fault inputs, when enabled, are all
normally open.
Below is a table with the terminal numbers and its
corresponding functions and default values.
Both
SAFE1
and
SAFE2
can be programmed to perform any of the following functions under the
LOGIC
sub-menu:

FUNCTION
DESCRIPTION
000
System reacts to the input in both opening (stops) and closing (reverses) cycles
001
Same as above. Requires the device to be supervised (FAULT active)
002
System reacts to the input only during the opening cycle (stops)
003
Same as above. Requires the device to be supervised (FAULT active)
004
System reacts to the input only during the closing cycle (reverses)
005
Same as above. Requires the device to be supervised (FAULT active)
006 BAR
Safety edge input. It reacts in both opening and closing. Stops and partially reverses.
007 BAR TEST
Same as above. Requires the device to be supervised (FAULT active)
008 BAR 8K2
