CAUTION: BE SURE CONTROL HOUSING IS PROPERLY GROUNDED.
The 530B Series uses a 7 position barrier type terminal strip to handle the power connections.
P1-1
(EARTH GROUND) - Ground the control by connecting the ground wire to this terminal. NOTE: Terminals P1-5 (-ARM)
and P2-2 (AMP REF) are electrically the same, which is the common reference point (low voltage common) for the control
logic. The EARTH GROUND terminal (P1-1) is electrically different from common. If connected together, either at the
amplifier or in any other fashion, fatal or hazardous operation may occur and permanent damage to the control WILL result!
P1-2
(AC1) 115VAC - Connect incoming hot AC (black wire) to this terminal. NOTE: This is fused (F1) on the control.
(AC1) 230VAC - Connect either hot side.
P1-3
(AC2) 115VAC - Connect the neutral AC (white wire) to this terminal. NOTE: This is fused (F2) on the control.
(AC2) 230VAC - Connect either hot side.
P1-4
(+ ARMATURE) - Connects to the plus (+) Armature wire on the motor. 0-90VDC for 115VAC input or 0-180VDC for 230
VAC input. See "SPECIFICATIONS" for output rating.
CAUTION: ARMATURE CONNECTION MUST NOT BE SWITCHED OR BROKEN WHILE CONTROL IS ON
OR SERIOUS DAMAGE TO THE CONTROL MAY RESULT.
P1-5
(- ARMATURE) - Connects to minus (-) Armature wire (also considered circuit common) on the motor.
P1-6
(- FIELD) - Connect minus (-) Field wire of the Shunt Wound motor (not used on PM motors).
P1-7
(+ FIELD) - DO NOT use for Permanent Magnet motor. This supplies + Field voltage for a Shunt Wound motor. See chart
above for dual voltage Field Wound motors. This output is rated at 1 Amp for 530B series controls and 1.5 Amps for the
533B control. For motors with dual voltage field (ie. 50/100V or 100/200V), make sure the highest value is connected.
The 530B Series uses a 13 position barrier type terminal strip for control connections.
CAUTION: NONE OF THE P2 TERMINALS SHOULD BE EARTH GROUNDED!
P2-1
(OVER CURRENT OUT) - Can be used to signal that the control is in current limit. It can also signal other devices or alarms.
This is a low level logic signal which goes "high" when the current limit amplifier is in current limit. The logic of this control
is +12 volts, while the output at this terminal is approximately 1.5 volts through a 1000Ω resistor when in Current Limit.
P2-2
(AMP REF) - This is the common point of the logic. It is used as common with OVER CURRENT OUT (P2-1), +TACH (P2-
9), REV 1 (P2-7), REV 2 (P2-8), and WIPER (P2-4). NOTE: Never connect this terminal to earth ground !! Serious damage
and injury may result !! This terminal is electrically the same point as -ARM (P1-5).
P2-3
(SPEEDPOT LO) - Connects to the low side (orange wire) of the 5K Speedpot (normally the CCW end). This input is raised
and lowered by the MIN trimpot. Electronic speed input voltage (voltage follower) may be referenced to Speedpot LO if
the
MIN trimpot adjustments are to be active. Otherwise, inputs may be referenced to AMP REF (P2-2), which will bypass
the
MIN trimpot. INPUT MUST NOT BE GROUNDED !
THE INPUT CONNECTION TO THE SPEEDPOT MUST NOT BE GROUNDED !!
SERIOUS DAMAGE TO THE CONTROL MAY RESULT FROM A GROUNDED INPUT.
P2-4
(SPEEDPOT WIPER) - Connects to the wiper (red wire) of the Speedpot (center lead). Use this input for the plus (+) side
of voltage follower operation or tach follower. The minus (-) side connects to AMP REF (P2-2). INPUT MUST NOT BE
GREATER THAN +12V MAXIMUM AND MUST NOT BE GROUNDED !
P2-5
(SPEEDPOT HI) - Connects to high side (white wire) of the Speedpot (CW end). This is internal +12 volts. INPUT MUST
NOT BE GROUNDED !
P2-6
(SPARE) - This terminal is not connected to the control circuit. It can be used as a terminal for field modifications.
