  • Page 5: Product Description

    Product Description The Series S1501 system is a microprocessor based alarm, shutdown, and control system with tachometer/hourmeter function. It tells in alphanumeric characters which protective device has signaled an alarm or caused equipment shutdown. Application programming is completed at Murphy and can be changed in the field. The system consists of: ...
  • Page 6 Control Relays The power supply has seven control relays to provide form “C” SPDT outputs for control functions of either the engine or electric motor application. Terminal Block Assembly Each sensor input terminal block consists of a 64-position, 32 pair input rail-mount terminal block for interface of panel or field-mounted end devices.
  • Page 7 Opto-Isolated Tach/Run Input The S1501 features an opto-isolated tach/run input located within the explosion-proof power supply. This special input is used for Run Input Sensing from a CD ignition, Magnetic Pickup, Motor Auxiliary Signal, or AC or DC run signals meeting the opto-isolated Tach/Run input specifications (refer to the Specifications section of this manual).

  • Page 8: Installation

    Installation Perform the mounting operation with power source off. WARNING: The S1501 Head was designed to be mounted within a weatherproof enclosure. It is intended for mounting in a flat panel. First, cut a square mounting hole of 3-5/8 in. (92 mm) x 3-5/8 in. (92 mm). Insert the Head from the front side of the panel and install the two mounting clamps, one on each side of the case, (see mounting clamp detail).
