SAFETYLIGHT SCREENS System Power RequirementsUSCD-.. models: 115/230V ac ±15% (50/60 Hz), 55 VA USCT-.. models: 24V dc ±15% @ 1.5 amp max.
Industrial fuse Rating (F2)115V ac: 1 amp, 250V ac; 230V ac: 0.5 amp, 250V 24V dc: 2 amp, 250V Response TimeLight Screens: Less than 38 milliseconds E-Stop: Less than 15 milliseconds
EZ-SCREEN ® Status IndicatorsControl Box and Receiver: Solid LED Flashing LED
Red BLOCKED/LATCHED LOCKOUT Green CLEAR BLANKING ON
PICO-GUARD ™ Yellow RESET Double Flash = Waiting for System Key RESET at Power-up Single Flash = ALIGNMENT. Flash rate in creas es with the number of sensing beams “made”, solid yellow when aligned and defined area is clear
MICRO-SCREEN ® Diagnostic Indicator Two-digit numeric display indicates cause of lockout condition and total number of beams blocked.
MINI-SCREEN ® Controls and Adjustments Keyed RESET of system lockout and latched conditionsFloating blanking
selection switches and fixed blanking programming switches
Auto Power-up On-Off switches E-Stop Switch Input The
Emergency stop switch must offer two normally closed contacts and be capable of switching 50 mA @ 30V dc. Total resistance, including wiring and all switches, must not exceed 30
EZ-SCREEN ® TYPE 2 for proper operation. Functional stop category 0 per NFPA 79 and EN 418, Safety Category 4 per EN 954-1. Simultaneity requirement less than 100 milliseconds. External Device Monitoring(
EDM) Input* Test
Input terminals must open within 200 milliseconds of the FSD outputs
closing (i.e., a clear condition) and must close within 200 milliseconds of the FSD outputs opening (i.e., a blocked condition) or a lockout will occur. The monitoring contacts must be forced-guided (or captive contact) to maintain control reliability of the machine control circuit and must be capable of reliably switching 15 to 50V dc at 20 to 100 mA. Terminals must be closed for a minimum of 0.05 seconds in order to guar an tee a test input signal. The switch-ing device used must be capable of switching 15-50V dc at 20 to 100 mA. Reset Input Terminals must be closed for a minimum of 0.5 seconds in order to guarantee a reset. The switching device must be capable of switching 15-50V dc at 20-100 mA. Auxiliary Monitor Relay
Reed relay; 125V ac or dc max., 500 mA max. (10 VA max., resistive load) Safety Outputs Forced-guided contact relay (resistive load). USCD-..2 & USCT-..2: FSD1 & 2, SSD = 250V ac max., 4 amp max. USCD-..3 & USCT-..3: FSD1 & 2, CNC = 250V ac max., 6 amp max. SSD = 250V ac max., 4 amp max. Mechanical life: 10,000,000 operations (minimum). Electrical life: 100,000 operations (typical @ 1.0 kVA switching power). Arc suppression is recommended when switching inductive loads. EnclosureMaterial: Welded
steel box with black polyester
powder paint finish Rating: NEMA 13; IEC IP64 Operating ConditionsTemperature: 0° to +50° C Relative humidity: 95% maximum (non-condensing) FMEA Tested Per re quire ments IEC 61496-1 (type 4) Applications Notes Use of fixed blanking requires sensors with 16 or more light beams. Up to 12 beams or 30% of the total number of beams in the array may be blanked, whichever is less. Call factory for applications assistance if a greater number of blanked beams is required.
