Response Time Standard and Long-Range Emitters/Receivers:
Less than 48 milliseconds using emitter/receiver with 114 mm to 406 mm defined area
Less than 60 milliseconds using emitter/receiver with 508 mm to 813 mm defined area
Less than 72 milliseconds using emitter/receiver with 914 mm to 1219 mm defined area
Heavy-Duty Emitters/Receivers:
Less than 48 milliseconds using emitter/receiver with 610 mm to 813 mm defined area

Status Indicators
(on control box and receiver)
Solid LED Flashing LED
Red BLOCKED/LATCHED LOCKOUT
Green CLEAR BLANKING ON
Yellow RESET Double Flash = Waiting for Power-up Key Reset
Single Flash = ALIGNMENT. Flash rate increases with the number of
sensing beams “made”, solid yellow when aligned and
defined area is clear
Diagnostic Indicators MSCT-2.. & MSCD-2..:
Two-digit numeric display indicates cause of lockout condition.
Display is visible through a window in the control box cover.
MSCA-1.., MSCB-1.. & MSCT-1..:
Four LEDs indicate cause of lockout condition.
Diagnostic LEDs are visible through a window in the control box cover.
Controls and Adjustments Keyed Reset of system lockout or latched conditions
Floating Blanking selection switches and Fixed Blanking programming switches
Auto Power Up On-Off switches
Test Input 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.
External Device Monitoring
(EDM) Input
Terminals must be closed before controller attempts to reset (close) the FSD outputs after clearing an
interruption of the defined area. The EDM input should open when the FSD outputs close (a clear condition),
but this is not required. The EDM input must be closed within 200 milliseconds of the FSD outputs opening (a
blocked condition) or a lockout condition will occur. The contacts of the monitored device must be capable of
switching 15-50V dc at 20 to 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).
MSC..-..2: FSD1 & 2, SSD = 250V ac max., 4 amp max.
MSC..-..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.
Enclosure Material: Welded steel box with black polyester powder paint finish.
Rating: NEMA 13, IEC IP64
Operating Conditions Temperature: 0° to +50° C Relative humidity: 95% maximum (non-condensing)
FMEA Tested Per requirements IEC 61496-1 (type 4)
Application 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.
