triggered by pressing the test key. This function test is not carried out
automatically when switching on the VEGATOR 121.
Note:
When connecting sensors without this defined switching sequence,
the switch-on monitoring must be deactivated.
With these switches you can delay the changeover of the relays by
the set time. This can be useful, e.g. with fluctuating product surfaces,
for preventing unwanted switching commands. The switch-on/off
delays can be set independently of each other. If both switches, e.g.
of the switch-on delay, are activated, the times sum up. Delays of 2, 6
or 8 seconds can thus be adjusted.
Information:
Keep in mind that the switching delay of the sensor and controller
accumulate.
A second relay can be ordered as an option for VEGATOR 121. The
function of the second relay is determined via this DIL switch. It can
be configured as fail safe relay or as second level relay. When config -
ured as level relay, the switching behaviour is identical to relay 1. If the
instrument is WHG approved, then both relays can be used as WHG
relay.
When level switches VEGAVIB, VEGAWAVE, VEGASWING in two-
wire version are connected, a function test can be carried out. The
test key is recessed behind the front plate of the controller. Press the
test key for at least one second with a suitable object (screwdriver,
pen, etc.).
Note:
Keep in mind that downstream connected devices are activated dur-
ing the function test. This allows you to check the correct function of
the complete measuring system.
By pushing the test key, the circuit to the sensor is interrupted and a
restart of the sensor is initiated. Through this, the conditions fault sig-
nal, empty and full alarm are simulated. The complete test procedure
takes approx. 5 seconds. After correct function, the red failure LED
should not light and depending on the status of the sensor, the relays
are energized or deenergized.
If the test result is negative, the red failure LED lights up and the
relays must be deenergized. In this case the whole measuring system
has to be checked and repaired.
Information:
This test is accepted as proof test acc. to WHG.
6.3 Automatic function test
As an alternative to the manual test via test key, the function test can
be also carried out automatically. For this purpose, the VEGATOR 121
