Operating modes (see Fig. III for function diagrams)
Function A: ON-delay
Function b: Pulse-shaping
Function C: OFF-delay
Function H: Passing make contact
Function d: Flasher; repeat cycle; starting with interval
Function di: Flasher; repeat cycle; starting with pulse
Programming (see fig. IV)
•To program, simply set the switch on the side of the unit to
the ON position.
•If the timer has started running, the time delay values:
- are taken into account immediately if your display is on the
up count (Up) and if the new value is greater than the time
that has already elapsed,
- will be taken into account in the next cycle if you are on a
down count display (down)
•The unit is supplied with the following configuration: 01.00 s,
d (down), C (mode), Prog = ON
•If, inadvertently, you enter the unit test procedure with the
entire screen or certain segments of the screen flashing,
press the MODE push-button until Bp is obtained on the
screen, then press VALID to return to normal operation.
•Incrementation of value T by pressing one of the 4 keys Ë
corresponding to each digit.
Utilization precautions
•The power cables and input circuits must be separate.
•A minimum requirement for ventilation and protection from
vibration must be provided.
ATTENTION
This equipment contains a lithium battery, do not
incinerate the unit.
