The Impulse is independent of S.
function L = Pulse shaping with retrigger function L = Pulse shaping with retrigger function :

S continuous ON has no effect on R.
function LS = Step-on step-off, with time lapse LS = Step-on step-off, with time lapse :
Control input S ON activates output R for the time t.
R is switched off immediately when a new control input is applied to S.

function M = Pulse shaping M = Pulse shaping :
Output R is activated for time t with control input S OFF.
The time cycle is independent of S.
function N = One shot trailing edge N = One shot trailing edge :
Output R is activated for time t with control input S OFF.
R is switched off immediately when a new control input is applied to S.
function P = Repeat cycle timer, interval start P = Repeat cycle timer, interval start :
Energizing of S ON activates output R periodically; starting with pause.
Pause (t1) and Pulse (t2) are independently adjustable of each other.
R is OFF immediately with S OFF.
Remark:
Allocations of t1 / t2 are solved differently for units of type C50.
function Q = One shot leading and trailing edge Q = One shot leading and trailing edge :
Control input S ON activates output R for the time t.
R is activated for the time t2 with control input S OFF.
Times t1 and t2 are independently adjustable of each other.
function S-SS = Step-on step-off S = Step-on step-off :
With S ON the output R switches, that means depending to the previous status ON or OFF.
Je nach Gerät ist der Ausgangszustand netzausfallsicher gespeichert (z.B. AS1), oder aber der Ausgangszustand wird mit Netz aus zurückgesetzt (z.B. AL).
SS = Step-on step-off ( not power failure protected ) :
With S ON the output R switches ON.
With S ON again, the output R switches OFF.
With suppy voltage OFF, reset and R switch OFF.
function SK = Step-n step-off with one shot leading edge SK = Step-n step-off with one shot leading edge :
With S ON the output R switches.
With S ON again before time release R switches immediately.
With line OFF the function is reset.
function UV = Pulse sequence monitoring U = Pulse sequence monitoring :
With monitoring clearance by S1 (Y1) i.e. without start cycle bridging, R is activated with the first correct input cycle.
With monitoring clearance by S2 (Y2) i.e. with start cycle bridging (tA), R is activated immediately.
R is deactivated after the time delay tV if the pulse cycle is to long.
R is deactivated for at least 50ms if a failure is detected:
R is activated again with the next recognized correct pulse cycle.
Application note:
This function monitors pulses for correct timing.
It is possible to monitor minimum speeds and motion cycles.

V = Pulse sequence monitoring :

R is deactivated after the time delay tV if the pulse cycle is too long.
R is deactivated for at least 50ms if a failure is detected:
R is activated again with the next recognized correct pulse.
Application note:
This function monitors pulses for correct timing.
It is possible to monitor minimum speeds and motion cycles.
function W = One shot leading edge W = One shot leading edge :
Control input S ON activates output R for the time t.
function X1 = Restart delay X1 = Restart delay :
Control input S ON (= operating voltage) activates output R immediately.
R is OFF immediately with S OFF.
R is reactivated only after the time t if S is ON before the set time cycle has expired.
function Y = Star-delta timer Y = Star-delta timer :
Control input S ON activates output R Star for the time t.
After the dead interval t Star - Delta (contactor switch over time), the output R Delta is activated.
The control input is made via A1 - A2.
Important note:
Outputs R Star and R Delta are internally interlocked.
