Once the above has been carried out, the system is now ready to be powered up.
The CaterSense-02 unit is pre-set to close the gas solenoid valve if it detects gas pressure
below 12 mbar. The unit also tests the integrity of the pipework during every start up by
opening the gas valve for 10 seconds, and then closing it for 30 seconds. If a significant drop
in pressure is detected during this time, the CaterSense unit will not open the valve. The
CaterSense-02 has an inbuilt facility to open the gas valve for a maximum of 5 minutes to
allow for system checking.
The gas valve will open for a maximum of 5 minutes to allow for system checking. The
internal gas pressure test can then be activated.
Ensure the fans are running at the lowest speed. Allow system to run and settle.
If the fan is monitored via an external source, and the "fan healthy" signal is provided from a
volt-free contact, ensure that the contact is closed.
