Normally open switch that will close with an increase of a specific condition (temp-press-etc.).
Normally open switch that is closed due to an applied condition, and will open again with a
specific decrease in that condition.
Normally closed switch that will open with an increase of a specific condition.
Normally closed switch that is open due to an applied condition, and will close again

The circle indicates that the component has screw terminals and a wire can be disconnected
from it.
No circle indicates that the wire cannot be disconnected from the component.
This indicates that the component has a wire connected to it that is connected to ground.
This indicates that the component does not have a wire connected to ground. It is grounded
by being fastened to the machine.

FUSE - A component in an electrical circuit that will open the circuit if too much current flows
through it.
REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet closes the
contacts of a normally open reed switch; it opens the contacts of a normally closed reed switch.
SENDER - A component that is used with a temperature or pressure gauge. The sender
measures the temperature or pressure. Its resistance changes to give an indication to the
gauge of the temperature or pressure.
RELAY (Magnetic Switch) - A relay is an electrical component that is activated by electricity.
It has a coil that makes an electromagnet when current flows through it. The electromagnet
can open or close the switch part of the relay.
CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the circuit if too
much current flows through it. This does not destroy the circuit breaker and it can be reset to
become part of the circuit again.
SOLENOID - A solenoid is an electrical component that is activated by electricity. It has a coil
that makes an electromagnet when current flows through it. The electromagnet can open or
close a valve or move a piece of metal that can do work.

MAGNETIC LATCH SOLENOID - A magnetic latch solenoid is an electrical component that is
activated by electricity and held latch by a permanent magnet. It has two coils (latch and unlatch)
that make electromagnet when current flows through them. It also has an internal switch that places
the latch coil circuit open at the time the coil latches.

NOTES:
WITH A BALANCED THREE PHASE LOAD AND UTILITY POWER FACTOR, THE
CURRENT TRANSFORMERS SHOULD BE WIRED IN THE CORRECT POTENTIAL LEG
AND MUST BE PHASED AT THE CONTROL AS FOLLOWS:
PHASE A: POTENTIAL TERMINAL 1, WITH RESPECT TO NEUTRAL, IN PHASE
WITH CT TERMINALS 4 TO 5.
PHASE B: POTENTIAL TERMINAL 2, WITH RESPECT TO NEUTRAL, IN PHASE
WITH CT TERMINALS 6 TO 7.
PHASE C: POTENTIAL TERMINAL 3, WITH RESPECT TO NEUTRAL, IN PHASE
WITH CT TERMINALS 8 TO 9.
POWER SOURCE CURRENT TRANSFORMERS SHOULD BE SIZED TO PRODUCE 5A
SECONDARY CURRENT WITH MAXIMUM GENERATOR CURRENT. CT BURDEN IS
ESSENTIALLY 0 VA.
CONTACTS TO CLOSE WHEN BREAKER CLOSES.
THIS CONTROL CONTAINS INTERNAL BURDEN RESISTORS. THESE BURDEN
RESISTORS MUST BE CONNECTED ACROSS POWER SOURCE CURRENT
TRANSFORMERS WHENEVER UNIT IS RUNNING TO PREVENT LETHAL HIGH
VOLTAGE FROM DEVELOPING ON LEADS TO THESE TERMINALS.
JUMPER 15 TO 16 AND 17 TO 18 WHEN POTENTIAL INPUT AT TERMINALS
1 THRU 3 IS 95 TO 130VAC PHASE TO PHASE (50-400HZ).
JUMPER 16 TO 17 WHEN POTENTIAL INPUT AT TERMINALS 1 THRU 3 IS 190
TO 260VAC PHASE TO PHASE (50-400HZ).
POTENTIAL TRANSFORMER BURDEN IS 5VA PER PHASE WITH 230VAC INPUT
AND 2.5VA PER PHASE WITH 115VAC INPUT.
CONTROL SIGNAL LINES SHOULD BE TWISTED PAIRS. SHIELD IS
TO BE TIED TO GROUND AT MODULE END ONLY.
