MTS-20H/30H & SCU-200 Data Sheet - Electro-Sensors, Inc.

Time Delay AdjustmentThe Relay Output Time Delay function is adjustable from 1-99seconds. Use a small screwdriver to turn the rotary switchesS2 and S3 for the desired time delay interval. Switch S2adjusts for single seconds, and switch S3 adjusts for tens.Example: A time delay of 14 seconds wouldrequire S3 to be set at 1 and S2 to be set at 4.Probe Status SwitchWith the probe status switch in the “A” position, the relay isenergized, and the green “SAFE” lamp is lit when the probeis tilted. With the probe status switch in the “B” position,the relay is energized and the green “SAFE” lamp is litwhen the probe is in a vertical position.Standard Probe ConnectionsAll tilt switch probes should be connected to terminals TB2-2 and TB2-3.Alternate Sensor ConnectionsSensor Power TB2-1Sensor Signal TB2-2Sensor Ground TB2-3Specifications • SCU-200 Control UnitInput Power ...................................... 115 Vac ± 10% 50/60 Hz.Opt. 230 Vac, 12/24 VdcProbe Signal Voltage ................ +12 Vdc (10 kΩ pull-up to+12 Vdc)Auxiliary SensorSupply Voltage................................ +12 Vdc @ 17 mA maxRelay Output ....................................
