Metal Box Controller with Muting Specifications

SAFETYLIGHT SCREENS Safety Outputs Forced-guided contact relay (resistive load). USCC-..2: FSD1 & 2, SSD = 250V ac max., 4 amp max. USCC-..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.
EZ-SCREEN ® Mute Lamp Output A monitored or non-monitored (selectable) sinking output. If monitoring has been selected, the current draw must be within 10 mA to 360 mA.
PICO-GUARD ™ Max. switching voltage: 30V dc Max. switching current: 360 mA
MICRO-SCREEN ® Max. switching current: 10 mA Saturation voltage: 1.5V dc
MINI-SCREEN ® Auxiliary DC Supply Output 24V dc ± 25%, 500 mA max
EZ-SCREEN ® EnclosureMaterial: Welded steel box with black polyester powder paint finish.
TYPE 2 Rating: NEMA 13; IEC IP64 Operating ConditionsTemperature: 0° to +50° C Relative humidity: 95% maximum (non-condensing) FMEA Tested Per requirements of 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.

DIN Module Controller Specifications

System Power Requirements 24V dc ±15%, 10% max. ripple, 1.5 amps max. Fuse Rating 2 amp, 250 V (3 AG or 5 x 20 mm slow blow) Response TimeLight Screens: Less than 38 milliseconds E-Stop: Less than 15 milliseconds Status Indicators Control Box and Receiver: Solid LED Flashing LED Red BLOCKED/LATCHED LOCKOUT
(on control module and receiver) Green CLEAR BLANKING ON 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 Diagnostic Indicator Two-digit numeric display indicates cause of lockout condition and total number of beams blocked. 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 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.
(except EDM models) Terminals must be closed for a minimum of 0.05 seconds in order to guarantee a test input signal. The switching device used must be capable of switching 15-50V dc at 20 to 100 mA. AUX Non-Safety Output Contact Reed relay; 125V ac or dc max., 500 mA max. (10 VA max., resistive load)
* External Device Monitoring (EDM) models only.
