Start-up
Be prepared to make an emergency shutdown when starting the
engine, turbine, or other type of prime mover, to protect against
runaway or overspeed with possible personal injury, loss of life, or
property damage.
Electrostatic Discharge Awareness
Electrostatic
Precautions
Electronic controls contain static
-
sensitive parts. Observe the
following precautions to prevent damage to these parts:
•Discharge body static before handling the control (with power to
the control turned off, contact a grounded surface and maintain
contact while handling the control).
•Avoid all plastic, vinyl, and Styrofoam (except antistatic
versions) around printed circuit boards.
•Do not touch the components or conductors on a printed circuit
board with your hands or with conductive devices.
To prevent damage to electronic components caused by improper
handling, read and observe the precautions in Woodward manual
82715 , Guide for Handling and Protection of Electronic Controls,
Printed Circuit Boards, and Modules.
Follow these precautions when working with or near the control.
1. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic
materials. Wear cotton or cotton-blend materials as much as possible because these do not store
static electric charges as much as synthetics.
2. Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary.
If you must remove the PCB from the control cabinet, follow these precautions:
•Do not touch any part of the PCB except the edges.
•Do not touch the electrical conductors, the connectors, or the components with conductive
devices or with your hands.
•When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in
until you are ready to install it. Immediately after removing the old PCB from the control cabinet,
place it in the antistatic protective bag.
External wiring
connections for reverse
-
acting controls are identical
to those for direct-acting controls.

General Information
The SPC (Servo Position Controller) is available in two model configurations:
8200-226: DeviceNet Control with Analog Backup (or Analog primary demand)
8200-227: CANopen Control with Analog Backup (or Analog primary demand)
Models 8200-224 & 8200-225 are inactive and replaced by above item numbers.
The SPC positions a hydraulic or pneumatic actuator based on a position demand signal received from a
control. The SPC positions a single-coil actuator using single or dual position feedback devices. The
position demand signal can be sent to the SPC via DiviceNet or CANopen, (4 to 20) mA, or both. A
software program running on a Personal Computer (PC) allows the user to easily configure and calibrate
the SPC.
Figure 1-1. SPC Connections
The SPC Service Tool is used to configure, calibrate, adjust, monitor, and troubleshoot an SPC. The
service tool runs on a PC and communicates with the SPC through a serial connection. The serial port
connector is a 9-pin sub-D socket and uses a straight-through cable to connect to the PC. Woodward
offers a USB to 9-pin Serial Adapter kit if needed for new computers that do not have a 9-pin serial
connector (P/N 8928-463). This kit contains a USB adapter, software, and a 1.8 m (6 feet) serial cable.
(See Chapter 4 for SPC Service Tool installation instructions.)
The SPC is configured by using the SPC Service Tool's configuration file editor to create a file that is then
loaded into the SPC. The SPC Service Tool can also read an existing configuration from an SPC into the
configuration file editor.
See Chapter 4, SPC User’s Guide, for detailed instructions on using the SPC Service Tool.
The first time an SPC is connected to an actuator, it must be calibrated to the actuator's position feedback
transducer. The user is guided through the calibration process by the service tool. Calibration can also be
performed by the control via the Digital Control link (DiviceNet or CANopen). The calibration procedure
can be found in the GAP help file.

Installation
Power Requirements
The SPC requires a voltage source of (18 to 32) V (dc), with a current capacity of 1.1 A max. If a battery
is used for operating power, a battery charger is necessary to maintain a stable supply voltage. The
power line should be protected with a 5 A, 125 V fuse capable of withstanding a 20 A, 100 ms in-rush
when power is applied.
The SPC is not equipped with input power switches. For this reason,
some means of switching input power must be provided for
installation and servicing.
To prevent damage to the control, make sure that the alternator or
other battery-charging device is turned off or disconnected before
disconnecting the battery from the control.
Location Considerations
Consider these requirements when selecting a mounting location for the SPC:
•Adequate ventilation for cooling
•Space for servicing and repair
•Protection from direct exposure to water
•Protection from high-voltage or high-current devices, or devices which produce electromagnetic
interference
•Avoidance of vibration
•Selection of a location that will provide an operating temperature range of
(–40 to +70) °C / (–40 to +158) °F
This product is intended for installation in an enclose
d industrial
control cabinet. In order to meet the requirements for Zone 2
Hazardous Location, the SPC must be mounted in an enclosure with
ingress protection of IP54 or greater.
Optional SPC Mounting Kit
Optionally, SPC mounting bracket kit #8928-7334 is available for use in reducing required panel mounting
space within a cabinet. Ideal for applications where multiple SPCs are utilized, this bracket allows SPCs
to be mounted such that they protrude vertically into the cabinet, reducing the required panel mounting
area. This bracket’s design allows users to first attach the SPC to the bracket, then install the entire
assembly onto a cabinet side panel. Please refer to
Figure 2-1.

Shields and Grounding
A shield termination is provided at the terminal block for each of the signals. All of these inputs should be
wired using shielded, twisted-pair wiring. The exposed wire length beyond the shield should be limited to
one 25 mm (1 inch). The shield should be terminated at only one end in order to avoid creating a ground
loop.

The SPC chassis must be connected to
PE Ground (Potential Earth)
using the grounding lug. The wire used for PE ground must be the
same size used for the input wires.
The SPC must be attached to protective earth by a ground strap or
otherwise, and all cables shielded to ensure electromagnetic
immunity integrity.
For best noise immunity, power cables should be run in separate
cable trays or conduits from the low-level I/O cables.
Terminal Block Connections
All inputs and outputs are made through spring-actuated terminal blocks. The spring clamp can be
actuated using the plastic lever included or by a standard 2.5 mm or 3/32 inch flat-bladed screwdriver.
The terminal blocks accept wires from (0.08 to 4) mm² / (26 to 12) AWG. The recommended strip length is
8 mm (0.3 inch).
Do not tin (sol
der) the wires that terminate at the terminal blocks. The
spring-loaded terminal blocks are designed to flatten stranded wire,
and if those strands are tinned together, the connection loses
surface area and is degraded.
See Figure 2-4 for the wiring diagram.
Actuator Driver Output
Connect shielded twisted-pair cable from actuator to ACT DRIVER+(1) and ACT DRIVER–(2). Connect
the cable shield to SHIELD (3) but do not connect the shield at the actuator end. The Actuator Driver
output is software configurable for ±10 mA, ±25 mA, ±50 mA, ±100 mA and ±250 mA ranges.
DC Transducer Input
If a (4 to 20) mA position transducer is used for feedback, connect shielded twisted-pair cable from
transducer to DC XDCR IN+(4) and DC XDCR IN-(5). Connect the cable shield to SHIELD(6) but do not
connect the shield at the transducer end.
Transducer Exciter/Transducer Power Output
If an AC transducer is used for feedback, this output is used as an exciter for the LVDT or RVDT.
Connect a shielded twisted-pair cable from the transducer excitation winding to XDCR EXC/PWR+(7) and
XDCR EXC/PWR-(8). Connect the cable shield to SHIELD (9) but do not connect the shield at the
transducer end.
If a DC transducer is used for feedback, this output is used to supply 18 V (dc) (120 mA max) for the
transducer power. Connect a shielded twisted-pair cable from the transducer power input to XDCR
EXC/PWR+(7) and XDCR EXC/PWR-(8). Connect the cable shield to SHIELD (9) but do not connect the
shield at the transducer end.
LVDT/RVDT Inputs
If an AC transducer is used for feedback, connect a shielded twisted-pair cable from each LVDT or RVDT
secondary to LVDT/RVDT 1A (13 & 14) and LVDT/RVDT 1B (16 & 17). Connect the shields to SHIELD
(15 &18).
If a redundant AC transducer is used, connect a shielded twisted-pair cable from each LVDT or RVDT
secondary to LVDT/RVDT 2A (19 & 20) and LVDT/RVDT 2B (22 & 23). Connect the shields to SHIELD
(21 & 24).
