The external safety input is controlled continuously.
If the “external safety” contact is open, it displays the fault
"EXTERNAL SAFETY"
, lights up the red fault indicator
light and inhibits the pump start-up. The output contact
7-8
is kept open.
• Before pressing on
"START"
,
the external safety input is not controlled.
• After pressing on
"START"
and during a delay
- of 4 seconds
if
SET START DELAY > 4 s
- or between 1 and 4s if
SET START DELAY
≤
4 s
the external safety input is not controlled.
• After this delay, this input is handled by the ACT.
If the “external safety” contact is open, it displays the
fault
"EXTERNAL SAFETY"
, lights up the red fault
indicator light, opens the output contact
7-8
and inhibits
the pump start-up.
This contact can be used to control the roughing pump
(see wiring example, following page).
If
SET START DELAY = 0
If
SET START DELAY
≠
0
Note: In "REMOTE" mode, after an external fault, the pump
must be set to the "STOP" status before starting up again.
