Parameters
4.10.3 13-1* Comparators
Comparators are used for comparing continuous variables
(such as output frequency, output current, and analog
input) to fixed preset values.

Comparator Value
Illustration 4.17 Comparators
In addition, there are digital values that are compared to
fixed time values. See the explanation in
parameter 13-10 Comparator Operand. Comparators are
evaluated once in each scan interval. Use the result (true
or false) directly. All parameters in this parameter group
are array parameters with index 0–5. Select index 0 to
program comparator 0, select index 1 to program
comparator 1, and so on.

Function:
Select the variable to be monitored by
the comparator.
Function:
Select [0] < for the result of the evaluation
to be true, when the variable selected in
parameter 13-10 Comparator Operand is
smaller than the fixed value in
parameter 13-12 Comparator Value. The
result is false, if the variable selected in

greater than the fixed value in
parameter 13-12 Comparator Value.
[1] Approx.Equal Select [1] ≈ for the result of the evaluation
(~) to be true, when the variable selected in
*
parameter 13-10 Comparator Operand is
approximately equal to the fixed value in
parameter 13-12 Comparator Value.
[2] Greater Than Select [2] > for the inverse logic of option

13-12 Comparator Value
Array [6]
Range: Function:
0 [-9999 - Enter the trigger level for the variable that is
*
9999 ] monitored by this comparator. This
parameter is an array parameter containing
comparator values 0–5.
4.10.4 13-2* Timers
Use the result (true or false) from timers directly to define
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 is 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.
13-20 SL Controller Timer
Array [8]
Range: Function:
0 s [0 - Enter the value to define the duration of the
*
3600 s] false output from the programmed timer. A timer
is only false if it is started by an action (see
parameter 13-52 SL Controller Action [29–31] and
parameter 13-52 SL Controller Action [70–74] Start
timer X) and until the timer value has elapsed.
Array parameters contain timers 0–7.
4.10.5 13-4* Logic Rules
Combine up to 3 boolean inputs (true/false inputs) from
timers, comparators, digital inputs, status bits, and events
using the logical operators AND, OR, and NOT. Select
boolean inputs for the calculation in parameter 13-40 Logic
Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2, and
