SECTION 6 - MAINTENANCE
This section contains maintenance procedures for the Valco MCP-4 Control.
A regular maintenance program helps ensure longer life and efficient
operation of your system. A few minutes spent on maintenance greatly
reduces downtime.
The system should be purged of air at every startup or shift change. To
purge the system, follow these steps:
1. Install the applicator head onto the contact glue valve.
2. Purge adhesive until no air is present and the glue flows evenly.
The glue valves can be purged
manually using an activator located on
the valve itself, by a solenoid-operated
air valve, or they can be purged using
the toouchscreen panel and control.
When using any valve in the top-down
position for the first time, it might be
necessary to remove the valve and
hold it so that the applicator head is at
the top. The fluid pressure should then
be set to 4 bar, and the solenoid should
be fired until all the air is out and a flow
of glue is present.
The type of downtime maintenance that is necessary for the MCP-4 Control
Unit depends on the length of time the unit is down.
During short periods of downtime, such as order changeover, follow these
steps:
1. Apply lithium grease or petroleum jelly to the orifice of the
applicator head (contact extrusion valve) to prevent dried
adhesive from clogging the valve.
2. Wipe the valve clean before restarting production.
For longer periods of downtime, follow these steps:
1. Remove the applicator head from the contact glue valve.
2. Install a stopper onto the contact glue valve in place of the
applicator head.
3. Flush the applicator head with clean water.
