Power On Delay 3s Response Time 15ms The inputs of the MSR38D/DP are the same as the MSR30. They can be connected to gate interlocks, e-stop devices or 4-wire safety mats. The gate interlocks and e-stops can be either single channel or dual channel normally-closed circuits. Recovery Time 20ms Indication LEDs Green = Power (Pwr) Green = K1 Closed Green = K2 Closed Pwr LED 3s Blink Diagnostics Constant 2 Blinks 4 Blinks Continuous Blinking Initialization Normal operation Config. change during operation Solid state output switch fault Internal Fault The reset capability of the MSR38D/DP allows it to set up for manual or automatic start and restart. The outputs include two delayed normally-open safety rated outputs that can be connected to loads up to 2A at 24V DC. These outputs can be used to send a safety stop signal to a machine or manufacturing system. The delay is accomplished by the configuration of jumpers on the terminals. The delay can be easily adjusted by reconfiguring the jumpers. The MSR38D/DP also has one solid state normally-closed auxiliary output, which must only be used to indicate the status of the MSR38D/DP. The auxiliary output responds immediately to the change in input status; it is not delayed.
