M‑7651A D‑PAC – Specification Settings Groups The M‑7651A D‑PAC has eight setting groups. Switch setting groups to properly account for prevailing power system conditions. For example if one breaker is dedicated for maintenance you can store the settings for all the feeders and use the appropriate group when that breaker is out of service for maintenance. All the functions shown in Figure 1 (Single Line diagram) are available in each settings group.
Page 26
This feature is only available with 10 mA, 50 mA, or 200 mA Ground CT Configurations. High Impedance Faults (HIZ) do not produce enough fault current to allow detection by conventional overcurrent methods. Beckwith Electric has developed a proprietary logic that uses harmonic components of Ground Fault Current (I ) to implement the SGI feature.
Page 27
M‑7651A D‑PAC – Specification Optional Arc Flash Protection The Arc Flash Protection option detects arc flash conditions in switchgear and operates circuit breakers to remove the current source from the arc, thus mitigating the potential damage to equipment. Four Optical Transceiver Ports interface to transparent fiber optic loops and/or point sensors. The output of the Optical Transceiver is compared to a pickup value.
Page 28
M‑7651A D‑PAC – Specification The sensor cable extension reach for each transceiver port is limited by the loss of optical signal strength in the fiber and each connector. Loop Sensors have the same loss rate as jacketed Cable Extensions at 0.22 dB per meter of fiber.

The M‑7651A D‑PAC also features a backup power supply input of 11 to 14 Vdc, that allows continued operation in case of main power supply loss.
Page 33
M‑7651A D‑PAC – Specification Output Contacts The M‑7651A D‑PAC includes four output contacts expandable to twelve. Any of the protective functions can be individually programmed to activate any one or more of the four Programmable Output Contacts (OUT1 through OUT4). Any output contact can also be selected as pulsed or latched. IPSlogic can also be used to activate output relay contact.

The Virtual Inputs can be assigned to any of the eight IPSlogic functions (Figure 3‑11). When the IPSlogic assigned to the selected Virtual Input operates, then the Virtual Input is asserted and the Function is blocked.
System Application & Function Setpoints – 3 The relay determines which input is the least significant bit. The physical input with the smallest number designator will be the least significant bit. For example, if Inputs 4, 6 and 8 are chosen then Input 4 will be the least significant bit preceded by Input 6 and finally Input 8 shall be the most significant bit.
