What Are Help Codes?

Help Codes are Error Diagnostic Codes. Each Gema™ Control Unit from OptiTronic® CG02-CG03

OptiStar® CG06-CG13

All display Error Codes with H##.

Identifying Help/Error Codes on Different Models

Gema™ OptiTronic® CG02 & CG03

On OptiTronic® CG02 & CG03, The Help Code will appear on the bottom right display. Where it says program underneath.

•Here is a list of Error/Help Codes

Help/Error Code	Fault Analysis
H01	Check Systerm Parameter P0 and set P0 = 0 on the basis control without FlowControl
H02	(Only Shows when FlowControl is fitted) Check Systerm Parameter P0 and set P0 = 0 on the basis control
H03	(Only Shows when FlowControl is fitted) Check Systerm Parameter P0 and set P0 = 0 on the basis control
H04	EL 1 Solenoid Valve Error, set System Parameter P5 = 0 for Automatic Equipment. Set P5 = 1 for Demo Equipment
H05	The desired Total Air is too little. Increase the programmed value for Total Air, or make the FL_min of the powder output correction smaller
H06	Main Solenoid Valve Fault. Connection Cable from the main solenoid valve to the basic electronics is missing. (Check the Main Solenoid Valve)
H07	The desired Supplementary Air Volume is too large (ZLmax.) Decrease the programmed value for the Total Air Volume and/or decrease the programmed value for the Powder Output Volume
H08	The desired Conveying Air Volume is too large (FLmax.) Decrease the programmed value for the Total Air Volume and/or decrease the programmed value for the Powder Output Volume
H09	The Daily Correction Value multiplied with the desired value of the Powder Output is greater than 100%. Acknowledge Error & decrease the Daily Correction Value via the PLC
H10	Gun Cascade produces too High Voltage. Check base electronics and Gun
H11	Check System Parameter P1 (Gun Type) Check Gun Cable for breaks, Replace Gun
H19	EL 2 Solenoid Valve Error (Not Used)
H20	Check the 24 V DC Internal Power Supply. The 24 V DC voltage is Higher than normal Voltage. (24 V DC-10%)
H21	Check the 24 V DC Internal Power Supply. The 24 V DC voltage is Lower than normal Voltage. (24 V DC-10%)
H22	Fault in the 15 V DC Power Supply to the basic electronics
H23	EEPROM Fault
H24	EEPROM writes Timeout

Gema™ OptiStar® CG06 & CG07

On OptiStar® CG06 & CG07, The Help Code will appear on the bottom Left display. Right above the +, -, & P Button

•The Error Codes are displayed in order of occurrence. Use the + & - Buttons to cycle through them

•Only the last 4 Errors will be stored. An Error will not store twice.

•It is possible an error will appear briefly then disappear. If this happens, Switch off Control Unit then power back on

•Here is a list of Error/Help Codes

Error/Help Code	Fault Analysis
H06	Trigger Value (Main Solenoid Valve) Solenoid Current is lower than present limiting value
H07	Supplementary Air Volume is too High (Total Air Setting on Display)
H08	Conveying Air Volume is too High (Powder % Setting on Display)
H09	Powder Output Higher than 100%
H10	Conveying Air Range lower than minimum range
H11	Gun Error, Check Gun & Gun Cable)
H20	Overvoltage +15V Supply
H21	Undervoltage +15V Supply
H22	Undervoltage -15V Supply
H23	Undervoltage +5V Supply
H24	EEPROM Content Invalid
H25	Timeout during EEPROM Writing
H26	Values not correctly storing in EEPROM during Switch Off
H60	Conveying Air Reference Position not found
H61	Supplementary Air Reference Position not found
H62	Electrode Rinsing Air Reference Position not found
H63	Shaping Air / Fluidizing Air Reference Position not found
H64	Conveying Air Throttle doesn't move
H65	Supplementary Air Throttle doesn't move
H66	Electrode Rinsing Air Throttle doesn't move
H67	Shaping Air / Fluidizing Air Throttle doesn't move
H68	Conveying Air Position Lost
H69	Supplementary Air Position Lost
H70	Electrode Rinsing Air Position Lost
H71	Shaping Air / Fluidizing Air Position Lost

Gema™ OptiStar® CG09 & CG13

•The Error Codes are displayed in order of occurrence. Use the <P> Arrow Buttons to cycle through them

•Only the last 4 Errors will be stored. An Error will not store twice.

•It is possible an error will appear briefly then disappear. If this happens, Switch off Control Unit then power back on
