(AI) ON delay.
Apply power to timer. Output contacts transfer after preset time
has elapsed. Reset occurs when power is removed.
(BE) Signal OFF delay.
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) Signal ON pulse.
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.
(SW) Symmetrical recycling: ON start.
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).

(DI) ON pulse.
Apply power to timer. Output contacts transfer immediately.
After the preset time has elapsed, contacts reset.

(CE) Signal ON and OFF delay.
Power is permenently applied to the timer.
Closing the Signal Switch (S) initiates the preset delay, after
which
time the output contacts transfer. Opening the Signal
switch initiates the same preset delay, after which time the
output contacts reset.

PAUSE (P)
Closure of the pause switch (2-5) will immediately halt the timing process,
but the elapsed time will be retained, and the current state of the output
contacts will be maintained.
On opening of the pause switch, timing resumes from the retained value.
This is applicable for all functions.
RESET (R)
A momentary closure of the reset switch (2-7) will reset the timer. Longer
term closure of the reset switch will hold the timer in the reset state. This
is applicable for all functions.
(Al a) ON Delay (2 timed contacts).
Apply power to timer.
Contacts (C1and C2) transfer after preset time has elasped.
Reset occurs when power is removed.
(Al b) ON Delay
(1 timed contact + 1 instantaneous contact).
Apply power to timer. Output contact (C1) transfers immediately.
Contact (C2) transfers after the preset time has elasped. Reset
occurs when power is removed.
(Dl a) ON pulse (2 timed contacts).
Apply power to timer.
Output contacts (C1and C2) transfer immediately.
After preset time has elasped, the contacts reset.
(Dl b) ON pulse (1 timed contact + 1 instantaneous contact).
Apply powert to timer. Output contacts (C1and C2) transfer
immediately. After preset time has elasped, the contact (C2)
resets. Contact (C1) resets when power is removed.
