WATER MANIFOLDS
Install and congure a Water Manifold
The M2-series controller provides a compact system for monitor-
ing the coolant system within a mould. Each controller may vary
slightly in its make-up but, generally, it comprises of a Controller
Cabinet with the following extras.
1. analogue input cards
2. other control cards as required
3. one or more water manifolds with ow
sensors and /or pressure sensors
4. sufcient data-cable to link the manifolds to the cabinet.
Installation
The water manifolds should be rmly mounted in a position that
will not be subjected to excess heat, vibration or other undue
stress.
The coolant system should be plumbed in by a qualied tter
ensuring that the exible coolant pipes are not trapped by mov-
ing parts or kinked by being stretched around corners or similar
obstructions. There should be a main ow and return shut-off valve
provided so that the water manifolds may be easily isolated for
repair or maintenance. You should not use any liquid sealant that
may contaminate the coolant circuits.
The cables that connect the water manifold to the controller are
marked for identication and should be connected to the appro-
priately marked sockets on the sensors and the controller. The
cables should be adequately supported using suitable cable tray
or individual cable cleats in accordance with the current IEEE Reg-
ulations for Electrical Installations.
Coolant Monitoring
It is possible to monitor up to three different coolant properties
using the following apparatus
Temperature – there is a choice of two main cards to monitor
water temperature
• the WT4 card has 12 T/C Inputs
• the 12RTD has 12 Resistive Temperature Device inputs and is
often the preferred device for this application
Flow – there are many analogue devices which give a standard
0-20 mA output that is proportional to the measured water ow –
any one of these devices may be connected to one or more of the
eight channels available on the AI8 Analogue card.
Pressure – like coolant ow above there are a choice of sensors
that give a 0–20 mA output. These can also be connected inde-
pendently to an AI8 card.
