5.11 DRY RUNNING PROTECTION
In the event of hose rupture on the high-pressure side or idle running, due to lack of
product, the pump runs too quickly. The system automatically closes the product valves
and issues a fault message.
Prevention
Perform the daily maintenance work stated in Chapter
Ensure a sufficient product supply at all times.
In the case of unforeseen occurrences, immediately perform emergency stop in
accordance with Chapter
5.12 HEATER (OPTION)
The electric, continuous-flow heater with explosion protection is downstream of the pump.
The coating product can only be heated to maximum 80 °C. The continuous-flow heater is
fitted with a temperature limiter.
The temperature is set using the temperature regulator. The coating product temperature
can be read off the thermometer on the coating product output.
For description, see heater operating manual.
5.13 AIS DOSING SYSTEM (OPTION)
The hardener dosing valve's stroke is regulated automatically via the AIS (option). The AIS
(Adaptive Injection System) dosing system optimizes injection amounts and cycles and
adapts these continually to the changing flow rates. Thereby, the AIS ensures optimum
dosing and constant coating quality.
Prerequisite: control unit 6, 8, 9 or 10.
AIS sets including conversion for control units 1 / 2 see Chapter

5.14 AUTOMATIC ELECTROSTATIC SYSTEM FOR ELECTROSTATIC GUN GM5000
(OPTION)
The TC VM5000 automatic electrostatic system serves as an additional safety device for the
safe use of the TwinControl 2K system with a GM5000 electrostatic gun.
However, the user has a duty to proceed in compliance with the instructions in Chapter
.
The automatic electrostatic system transmits the approval signal from a TwinControl
system (as of version 4.03) to a VM 5000 control unit. If the electrostatic system for the
gun may be switched on (after filling), the TwinControl system transmits the pneumatic
approval signal to the pressure switch. The pressure switch switches at a set pressure of,
e.g., 2 bar. The pressure switch is connected to the VM 5000 control unit via the interface
cable. The remote control function must be set in the VM 5000.
Control for the automatic electrostatic system: For installation possibilities in the
TwinControl control units, see Chapter
