Checking And Adjusting The Gas Flows; Checking Device Settings And Signals - Sony Multiscan CPD-1304S Service Manual

Commissioning and decommissioning

6.2.1 Checking and adjusting the gas flows

If you have done commissioning (steps 1 to 6 for start-up) and the right LED of the device is
flashing red, you have to customize the flow of the process gas. Given that the local conditions
are unknown and may differ with regard to the factory settings, it is possible that the internal
pressure is not sufficient.
In this case, try to increase the pressure of the process gas until it reaches 0.2 MPa (gauge). If
this is not possible or the pressure is even higher, gently twist the right needle valve until the LED
lights up permanently.
If the bypass is used, its flow must also be adapted to the conditions of the installation, this is
possible with the left needle valve. If the right LED flashes or flashes again after this setting,
perform a (re) correction on the right needle valve (as described above).
The device shows all dependent values (e.g. temperature, pressure, etc.) in RED
(as a fault) before they reach the measurement conditions and the right LED
flashes in RED.
If no errors are currently present, the LED lights up permanently. The color
depends on previous events. The values are displayed in BLACK text.

6.2.2 Checking device settings and signals

A complete review of the current device parameterization can be performed by using the enSuite
software with an online connection to the Q2.
See chapter 8. Parameterized output signals can be measured using appropriate measurement
devices and checked in that way.
Verifying digital communications (Modbus, etc.) may take place (e.g. as a protocol analyzer) Use
appropriate tools.
DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT
DISCONNECT POWER BEFORE OPENING
Only open under controlled conditions according to the ISO/IEC61010-1*
* These conditions (Temperature 5°C to 40°C; Humidity up to 80% at 31°C decreasing linearly to 50% at
40°C) usually prevail in residential and office spaces. In case of doubt please read the standard or contact
Elster GmbH.
