Supply Start = Start via contact in supply line (A1).
Control signal = Start via contact into control terminal (X-S).
(AI) On-delay.
Apply power to timer. Output contacts transfer after preset
time has elapsed. Reset occurs when power is removed.
(DI) Interval.
Apply power to timer. Output contacts transfer immediately.
After the preset time has elapsed, contacts reset.
(SW) Symmetrical flasher (starting pulse on).
Apply power to timer. Output contacts transfer immediately
and cycle between ON and OFF for as long as power is
applied. The ratio is 1:1 (time on = time off).
(SP) Symmetrical flasher (starting pulse off).
Apply power to timer. First transfer of contact occurs after
preset time has elapsed. The timer now cycles between OFF
and ON as long as power is applied. The ratio is 1:1 (time
on = time off).
(BE) Off-delay with control signal.
Power is permenently applied to the timer. The output
contacts transfer immediately on closure of the Signal
Switch (S). Opening the Signal Switch initiates the preset
delay, after which time the output contacts reset.
(DE) Interval with control signal on.
Power is permenently applied to the timer.
On momentary or maintained closure of Signal Switch (S),
the output contacts transfer, and remain so for the duration
of the preset delay, after which they reset.
(EEb) Interval with control signal off.
Power is permenently applied to the timer.
On opening of the Signal Switch (S) the output contacts
transfer, and remain so for the duration of the preset delay,
after which they reset.
Example:
Supply START; ON delay function
Closing the external reset switch immediately resets the
timer. Opening the reset switch re-initiates the timing
function.
Example:
Control signal; ON pulse function.
Closing the external reset switch terminates the interval time
and resets the timer. To re-start, it is necessary to open the
reset switch, before closing the control signal contact.
*Terminals R, S & X must
not be directly connected
to the timer supply voltage,
but they should be
considered to be at supply
voltage potential for the
purposes of insulation.
**Connection of the Reset
(R-X) is optional
For each and every
function and time range,
the timer is immediately
reset when the reset switch
is closed.
