OFF delay (R)
The supply voltage U must be constantly applied to the device (green
LED U/t illuminated). When the control contact S is closed, the output
relay R switches into on-position (yellow LED illuminated). If the control
contact is opened, the set interval t begins (green LED flashes). After
the interval t has expired (green LED U/t illuminated) the output relay
switches into off-position (yellow LED not illuminated). If the control
contact is closed again before the interval t has expired, the interval
already expired is erased and is restarted.
Functions
Load Alternator - Pump Changer (LA)
In this mode, every falling edge toggles the output relay R (flip-flop) from
L1 to L2 or L2 to L1 whatever position is defined by the previous status.
On Power-Up the relay R stays in off condition until the first falling edge is
detected on S Terminal B1.
To ensure a safe and optimal function, please turn both timing controllers
on the front to the most left position (CCW), which equals 50 msec.
In this operation mode, a minimum delay/de-bump time of 50 msec is
applied from the falling edge of the control input until relay R is changing
its state.
Is a longer delay time as 50 msec is set, a short pulse on the „S“ input
resets the times. The timer is restarted with the next falling edge signal on
„S“ input again. If you wish to apply longer delay times, set the according
time selectors to the required values or contact your application engineer.
Manual OFF (L1)
If the function selector indicates function L1, the output relay R remains
in the off-position. If you switch from LA to L1 the relay switches into
off-position independent of the status of the control input.
Manual ON (L2)
If the function selector indicates function L2, the output relay R remains
in on-position as long as the supply voltage is available. If you switch
from LA to L2 the relay switches into on-position independent of the
status of the control input.
ON delay (E)
When the supply voltage U is applied, the set interval t begins (green
LED U/t flashes). After the interval t has expired (green LED U/t
illuminated) the output relay R switches into on-position (yellow LED
illuminated). This status remains until the supply voltage is interrupted.
If the supply voltage is interrupted before the expiry of the interval t,
the interval already expired is erased and is restarted when the supply
voltage is next applied.
