EPG-SPRINT X
OPERATING MANUAL
VERSION 06/2014 ORDER NUMBER DOC2329371
Problems when combining eld controllers and guns:
When the control unit is operated in normal mode, the automatic spray current reset can
su er a functional fault when positive and negative cascades are combined if all of the
guns and eld controllers are not connected simultaneously.
Switching o the automatic spray current reset:
The automatic spray current reset can be switched o via con guration parameter
"C28 High-voltage module: Automatic spray current reset".
The spray current reset must then be performed manually. There are several ways of doing
this.
Spray current reset using the control unit:
When the EPG-SPRINT X control unit is powered up, the reset takes place via the control
unit itself.
For this reason, never switch a device on using the mains switch if guns or eld controllers
are already being used for spraying in the same system. The operator must ensure that this
cannot happen.
Basic conditions for manually resetting the spray current:
The operator or higher-level controller must ensure that no gun or eld controller (any
high-voltage module) has been used for spraying 10 seconds before the reset takes place.
Manual spray current reset option 1:
The reset can be performed by the operator. He/she is responsible for complying with
the basic conditions. The reset can be performed by holding down the characteristic
slope button for more than 2 seconds. If the reset has been successful, the 3 LEDs on the
characteristic slope button light up for approx. 2seconds in quick succession.
Manual spray current reset option 2:
If the purge function is carried out at the control unit, the spray current is reset once
following the completion of the purging process. If the EPG-SPRINT X is used as an
automatic gun control unit with an extended transfer protocol at the recipe input of the
remote control bush (C26 = "ON"), the reset is not performed during purging as a separate
command "63" is available.
Manual spray current reset option 3:
If the EPG-SPRINT X is used as an automatic gun control unit with an extended transfer
protocol at the recipe input of the remote control bush (C26 = "ON"), the reset can be called
up by sending command "63". (Further information can be found in the service manual in
the "Documentation for the Extended Transfer Protocol at the Recipe Input" chapter).
