Danfoss VLT AQUA FC 202 Design Guide

2 parameters are used, and the output can be used in the logic rules and as events.
R
S
Flip flop output

Illustration 40: Flip Flop Outputs
The 2 operators can be selected from a long list. As a special case, the same digital input can be used as both set and reset, making it
possible to use the same digital input as start/stop. The following settings can be used to set up the same digital input (for example,
DI32) as start/ stop.

6.2.12.5 Timers
Use the result (true or false) from timers directly to dene an event (see parameter 13-51 SL Controller Event), or as boolean input in a
logic rule (see parameter 13-40 Logic Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2, or parameter 13-44 Logic Rule Boolean 3). A
timer is only false when started by an action (for example [29] Start timer 1) until the timer value entered in this parameter has
elapsed. Then it becomes true again. All parameters in this parameter group are array parameters with index 0–2. Select index 0 to
program timer 0, select index 1 to program timer 1, and so on.
