Step 2. Decrease input current until PICKUP LED turns GREEN then OFF.
Step 3. Set TIME PICKUP to 0.44.
Step 4. Slowly increase current to terminals 5 and 6. PICKUP LED should change from GREEN to RED
at an input current of 0.426 to 0.454 amperes.
Step 5. Decrease input current until PICKUP LED turns OFF.
Perform preliminary setup:
INST Pickup Test
•
Connect test setup as shown in Figure 5-1.
•
Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON, and SW3-4 ON.
•
Set TIME DIAL to 0.0.
•
Set CURVE to S
•
Set TIME PICKUP to 3.18.
•
Set INST PICKUP to 0.2
Step 1. Slowly increase current to terminals 5 and 6. INST contacts should close at an input current of
0.191 to 0.209 amperes.
Step 2. Decrease input current until INST output contacts open.
Step 3. Set INST PICKUP to 08.
Step 4. Slowly increase current to terminals 5 and 6. INST contacts should close at an input current of
1.563 to 1.637 amperes.
Step 5. Decrease input current until INST output contacts open.
Perform preliminary setup:
Time Dial Test
•
Connect test setup as shown in Figure 5-1.
•
Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON, and SW3-4 ON.
•
Set TIME DIAL to 4.5.
•
Set CURVE to S
•
Set TIME PICKUP to 0.2.
•
Set INST PICKUP to 18.0.
Step 1. Prepare to apply 0.3 amperes input current to terminals 5 and 6 and record the elapsed time from
when current is applied until TIME output contacts close.
Step 2. Apply the current (step from 0 to 0.3 amperes) and record the elapsed time. Elapsed time should
be 0.345 to 0.424 seconds. (This tolerance is greater than ±2% because it is the accumulation
of both pickup and timing tolerances.)
Step 3. Remove input current.
Perform preliminary setup:
Target Test
•
Connect test setup as shown in Figure 5-2.
•
Insure that SW3 switches are set: SW3-1 for the operating frequency, SW3-2 to OFF, SW3-3 to
ON, and SW3-4 ON.
•
Set TIME DIAL to 4.5.
•
Set CURVE to S
•
Set TIME PICKUP to 0.2.
•
Set INST PICKUP to 19.8.
Step 1. Set voltage source to provide a target current of 1.0 ampere.
Step 2. Apply 1 ampere input current to terminals 5 and 6. Check that the TIME target operates.
Step 3. Remove input current and reset target.
Step 4. Set TIME PICKUP to 3.18 and set INST PICKUP to 0.2.
Step 5. Set voltage source to provide a target current of 1.0 ampere.
