START UP
- Wiring the probes.
Observe regulations for laying cables in potentially explosive atmospheres!
The intrinsic safety input circuits must not be earthed!
When extending the probe cable, shielded cable (min. 2x1mm²) should be used, the maximum cable length is 300m.
- Remove the cover of the sensor power supply unit (NivOil CU), carefully pull the ribbon cable to the front panel off the connector.
- Connect the probes according to the wiring diagram.
Note!
- Strip the probe and power supply cables to a max. length of 6cm and fit them with grommets or heat shrink tubing.
- Connect the sensor power supply unit (NivOil CU) properly to the power supply
- Plug the ribbon cable back onto the connector and screw the front panel tight.
- Switch on the supply voltage.
- Sensor supply unit (NivOil CU) performs self-testing (lamp test of all LEDs and the buzzer).
- The correct connection of the probes (short circuit/line break test) is checked.
- The probe / type recognition is running, i.e. the corresponding probe (NivOil OP, HP / HPS or SP) is recognised and assigned to the input
channel accordingly.
If the test is successful, the corresponding LED on the front panel lights up green.
- Successful check = a LED is lit permanently.
- Wrong probe = all 3 LEDs blinking.
- Channels that are not in use remain switched off.
- Inventory list:
When the unit is switched on for the first time, the electronics "remember" which probe is connected to which input in an inventory list.
A signal tone is emitted 2x during the test (factory setting = no probes connected).
This makes it possible to determine at any time whether the respective probes are working properly.
Behaviour when connecting an additional probe or when an existing probe is dismantled or reconnected:
- If a new probe is connected to a previously unoccupied channel, it is added to the inventory list when the supply voltage is switched on
again or by pressing the test button.
- If a probe is disconnected or reconnected, the probe is deleted from the inventory list as follows:
Press the reset button and hold it down for at least 5 seconds. (Buzzer beeps 5x)
- If a probe is disconnected and not deleted of the inventory, it is reported as faulty with the respective LED blinking.
ALARM REPETITION
The ''Alarm Repetition'' function can be switched on and off via DIP 2.
With DIP 2 = ON, the buzzer is triggered again 24 hours after an alarm has been acknowledged and is still pending.
(see case 3 of the alarm logic)
If this function is unwanted, DIP 2 must be switched to OFF.
