Zero-adjustment button Note: The analog current output is limited to a lower limit of 3 mA and an 0-ADJ. upper limit of 23 mA by a control circuit. Sensor head Press Span adjustment range • The output span (slope) can be adjusted with the ‘span Touch adjuster’ over a range of 0.7 to 1.3 times than that for the 5 Set the sensor head at the maximum distance [GP-A5S(I): standard sensing object. 1 mm 0.039 in, GP-A8S(I) and GP-A10M(I): 2 mm 0.079 in, GP-A12ML(I): 5 mm 0.197 in and GP-A14F(I): 3 mm 0.118 in] from the sensing object. At this time, adjust the analog voltage output to�5 V or 6.5 V Span adjuster the analog current output to 20 mA with the ‘span SPAN adjuster’. 5 V Sensing object 3.5 V Span adjuster 0.7 times 1.3 times SPAN Sensor head 0 V Maximum distance Maximum distance Note: Since the analog voltage output and the analog current output get adjusted simultaneously, it is not possible to adjust them individually. Note: Since the span adjustment can be done irrespective of the ‘button operation effective / ineffective selection switch’ position, do not operate the span adjuster after the adjustment. 6 Once again, touch the sensor head to the sensing object, Button operation 8 and confirm that the analog voltage output and the After the adjustment, make sure to effective / ineffective analog current output are 0 V and 4 mA, respectively. set the ‘button operation effective / selection switch In case they are not, repeat the adjustment from step 4. ineffective selection switch’ to the LOCK ‘LOCK’ side and close the cover on top of the amplifier. FREE • The values of zero-point setting and shift adjustment get stored in an EEPROM when the switch is set to the ‘LOCK’ side. The values stored in the EEPROM are not erased even when the power supply is switched off. However, kindly note that the EEPROM has a life span and its guaranteed life is 100,000 write operation cycles. Notes: 1) The set values are not stored in the EEPROM if the power supply is switched off when the switch is on the ‘FREE’ side. 2) If the switch is set to the ‘LOCK’ side before adjustment, the set values cannot be changed. 994 GP-A GP-X LD LA LA-300 HL-T1 LM10 LH-50 HL-C1 MEASUREMENT SENSORS Magnetic Displacement Light / Thru-beam Type Light / Reflective Type GP-A DIMENSIONS (Unit: mm in) The CAD data in the dimensions can be downloaded from the SUNX website: http://www.sunx.co.jp/ Sensor head Amplifier GP-A5S(I) All models "2.5 "0.098 high frequency 7 coaxial cable, 3 m 9.843 ft long 0.276 Connector 17 6.2 0.669 0.244 "5.4 17 "6.4 "0.213 0.669 "0.252 (100) 25.7 90 (3.937) 1.012 3.543 GP-A8S(I) "2.5 "0.098 high frequency coaxial cable, 3 m 9.843 ft long Connector 6.2 17 2 0.244 0.669 0.079 (119) 53 (4.685) 6.5 2.087 0.256 "8 Suitable for 35 mm 1.378 in width DIN rail 17 "0.315 "6.4 0.669 "0.252 25.7 Connector for sensor head connection 1.012 GP-A10M(I) 67 14 17 6.2 2.638 0.551 "2.5 "0.098 high frequency 0.669 0.244 coaxial cable, 3 m 9.843 ft long 3 19.8 0.118 Connector 0.780 17 18 " Cover removed condition " 0.669 6.4 0.709 " " 0.252 25.7 1.012 " 2-"5 0.197 Power indicator (Green) M10�1 0.039 Toothed lock washer (internal tooth) mounting holes Over indicator (Orange) 39 GP-A12ML(I) 2-"8.2 "0.323 1.535 Alarm indicator (Yellow) 56 7 8 6.2 21 "2.5 "0.098 high frequency 0.244 0.827 17 7 coaxial cable, 3 m 9.843 ft long 0.669 0.276 Connector 76 2.992 "10.1 "0.398 17 " 0.669 6.4 " 25.7 0.252 M12�1 0.039 12 3 4 "21 3.5 1.012 "0.827 0.138 Toothed lock washer (internal tooth) Shift-down button Shift-up button GP-A14F(I) Zero-adjustment button Span adjuster Button operation effective / ineffective selection switch 34 "2.5 "0.098 high frequency 5.4 1.339 coaxial cable, 3 m 9.843 ft long 0.213 27.5 1.083 7.5 8 Connector 0.295 0.315 15 0.591 17 " 6.4 0.669 " 0.252 25.7 1.012 Center of sensing 2-countersunk mounting holes for M3 MS-SS5 Mounting bracket for GP-A5S(I) (Optional), mounting bracket for GP-A8S(I) (Optional) MS-SS8 2 -"3.5 "0.138 mounting holes C Model No. MS-SS5 MS-SS8 Item A18 0.709 20 0.787 A B B10 0.394 11 0.433 4 0.157 C8.3 0.327 10.3 0.406 4 8 4 0.157 0.315 0.157 D6.1 0.240 6.5 0.256 16 D 0.630 Material: Nylon 66 Applicable model GP-A5S(I) GP-A8S(I) 995 Magnetic Displacement Light / Thru-beam Type Light / Reflective Type MEASUREMENT SENSORS GP-A GP-X LD LA LA-300 HL-T1 LM10 LH-50 HL-C1
