7.45 Reset of the maintenances
Display "Service" is on and the device functions complete-
ly normal.
Description applies to HDS devices with indicator lights
–
on the control panel.
When resetting the maintenances, the fault memory is
–
also deleted. (Delete faults only: Temperature control-
ler to 70 (52/44)°C and SET upon switch-on).
Maintenance due as one or several of the following condi-
tions has been reached:
80000 gun switching operations,
–
400 burner hours or
–
600 pump hours.
–
Print and cut out template (page 13).
–
Hold the template against the indicator lights on the
–
control panel.
Select the service mode.
–
(Switch off the device, put the service switch to "Ser-
vice", switch on device).
Query gun switching operations: Temperature controller to
80 (58/46)°C.
 80 (58/46)°C - Gun switching operations since the last
gun service (maintenance every 80000 switching oper-
ations).
 85 (60/48)°C - Number of gun services.
 85 (60/48)°C and Set upon switch-on - delete gun ser-
vice and fault memory.
 90 (63/50)°C - Total gun switching operations.
 95 (66/52)°C - Operating hours since last burner ser-
vice (maintenance every 400 h).
 100 (68/54)°C - Number of burner services.
 100 (68/54)°C and Set upon switch-on - delete burner
service and fault memory.
 112 (70/55)°C - Total operating hours burner.
 125 (74/56)°C - Operating hours since last pump ser-
vice (maintenance every 600 h).
 140 (77/58)°C - Number of pump services.
 140 (77/58)°C and Set upon switch-on - delete pump
service and fault memory.
 155 (80/60)°C - Total operating hours pump.
 Turn off the appliance.
