BE1-87G Testing Differential: Method 1 Set selector switch to D Apply 0.1 amps to terminals 9-6 Ramp up current to terminals 8-6 Relay should pick up

BE1-87G Testing Differential: Method 2 Set selector switch to D Apply 1.0 amps to terminals 9-8 at 1800 Apply 1.0 amps to terminals 6-8 at 00 and ramp

BE1-87G Investigate! Try changing angles (if you can)–does relay respond differently at 300, 900, 1800, etc.? Is there a maximum torque angle? Ramp up
