DXP-HT v1.3 - Programmer’s Guide
The Control Logic drop-down menu allows you to select from 3 control type options:
Latching
,
Momentary
and
Pulse Type
:
Latching
relays remain on until another relay is selected.
Momentary
relays will remain on as long as the touch button is being pressed.
Pulse Type
relays will turn on for ½ second and then will automatically turn off.
Latching relays can use one, two or three relays to control a motor controller. DXP-HT always
reserves 3 relays, but you can configure it to match the control method for your motor controller.
For motor controllers that use a single relay, define two relays, but only connect one. For example,
if relay 1 is engaged the screen goes down, when it is disengaged the screen goes up. By defining
two relays, when the down button is selected, relay 1 is disengaged and relay 2 is engaged.
Engaging relays two would of course do nothing.
Momentary and Pulse Type relays require a minimum of 2 relays to be defined. Momentary relay
control would be needed if the motor controller does not have limit switches to stop the motors.
DXP-HT does not support timed closures in place of limit switches. Timed closure control has
historically been unreliable, and is therefore not supported.
