Abnormal Situation And Alarm Notification; Interlock; Safe; Arcing - SAES SIP POWER User Manual

7. ABNORMAL SITUATION AND ALARM NOTIFICATION

In case of abnormal situations and/or alarms SIP POWER states the situation with a significant
word on the first line of the display.
At the beginning of the line a bell will be shown
multiple notifications are present.
In order to delete notifications from display it is necessary to press right key (
notifications are deleted in one shot).

Interlock

This alarm is shown when interlock input signal is missing. Check IN/OUT INTERFACE connector.
If contact is opened when the pump is already working, SIP POWER switches off immediately the
voltage supply which resumes when the contact is closed back. On the contrary if Interlock is open
in Stop status it is not possible to start supply.

Safe

This alarm is shown when safety input signal is missing.
If contact is opened when the pump is already working, SIP POWER switches off immediately the
voltage supply which resumes when the contact is closed back. On the contrary if Safety signal is
not present in Stop status it is not possible to start supply.

Arcing

During particular working conditions (for example the first pump switching on, or unexpected
pressure bursts), arcing may occur. Such events are characterized by direct current flow through
the ionized gas between anode and cathode. Such condition is detrimental for the pump since it
may accelerate the normal degradation process of the cathode surface.
SIP POWER electronic circuit is designed so that this phenomenon is automatically stopped. If
arcing is particularly strong or long SIP POWER switches off the voltage supply to the pump for
one or two seconds and raises an event. If arcing happens at least three times in less than 45
seconds the supply to the pump is stopped completely.
SIP POWER stores how many arcing events have happened since Start or since last deleting of
notifications. On the display, near the word Arcing, a # will be shown followed by the value of this
counter.

Over current

This alarm is shown when the power supply detects an output over-current event: if switch SW1
mode is set to ON and the output current increases over SW1 threshold. (See 4.3)
SIP POWER performs three retries of automatic restart: if Over Current happens three times in 45
seconds the supply to the pump is stopped completely and the corresponding Switch1 contacts on
IN/OUT INTERFACE connector present a closed contact permanently.

Over temperature

This alarm is shown when the power supply internal temperature increases over 80°C.
In case of Over Temperature the voltage supply is interrupted and restart automatically when the
