Connection Option Pneumatic Drive Ms1 Or Ms3; Electrical Connections - M&C SP Series Instruction Manual

 With option -H320/C it is possible to feed test gas via the standard connection for a 6mm tube that is equipped
with a blind cap for the measuring operation. It is placed directly below the heat conducting jaws. For the
connection of the calibration gas line, the blind cap must be removed. By means of the union nut that is attached
to the consignment, the calibration gas line can be connected.
Attention
 Optionally, the test gas feeding or back purging can be effected via a check valve -H320/R. The check valve is
mounted in the area of the bottom plate. The connecting line (tube/pipe, 6 mm outside diameter) can be con-
nected directly on the check valve.
 After having finished the mountage, put on again the protection cap and fasten it with the quick action locks.

Warning
Note
www.mc-techgroup.com
After the test gas feeding being finished, the connection must be shut again with the
blind cap because otherwise this connection would aspirate secondary air and falsify the
measuring result!
When connecting the equipment, please ensure that the supply voltage is identi-
cal with the information provided on the model type plate.
Attention must be paid to the requirements of IEC 364 (DIN VDE 0100) when set-
ting high-power electrical units with nominal voltages of up to 1000 V, together
with the associated standards and stipulations.
In any case we recommend the use of temperature resistant cable !
A main switch and matching fuse must be provided externally!
The main circuit must be equipped with a fuse corresponding to the nominal cur-
rent (over current protection); for electrical details see technical data.
It is recommended to use the low temperature alarm. In case of an alarm the flow
can be stopped and the components downstream the probe are safe for demage.
