MCP AND ELECTRICAL HOOK UP EIM E1195
MODULAR CONTROL
PACKAGE – MCP
Electrical components are EIM factory assembled, wired and tested as a module, with three possible MCP configurations.
1) MINI FRAME – Position Limit
Switches, Torque Limit Switches, and
Terminal Strip. (No Controls).
2) SHORT FRAME – Furnished when
Reversing Contactor or additional electrical controls are supplied.
3) FULL FRAME – Reversing Contactor with the addition of electronic plugin modules.
ELECTRICAL HOOKUP
STEP 1. Move valve to mid-position by handwheel. This will allow sufficient time to stop actuator in case of improper hookup or reversed power phases.
STEP 2. Identify a means of removing power from actuator during check out.
STEP 3. Be sure no erroneous remote control signal can be received causing actuator to energize.
STEP 4. Energize Open control to check operation of contactor and push buttons.
Open controls must move valve in Open direction. If valve Closes, actuator must be stopped and the power leads reversed to correct voltage phasing or improper field wiring.
CAUTION: If voltage is improperly phased, Torque and Limit Switches are not in circuit to protect valve.
STEP 5. Seal all field conduit entries in accordance with National Electric Code requirements.
EIM Modular Control Package (MCP) is available configured in thousands of possible combinations of electrical and electronic parts.
Refer to WIRING DIAGRAM and EIM JOB SPEC SHEET provided by EIM with each actuator.

GEARED ROTARY LIMIT SWITCH SETTING INSTRUCTIONS EIM E1195
BEFORE MAKING ANY SWITCH
SETTING:
1. Move valve to mid-position using handwheel.
2. Phase the power (motor) voltage and make sure that open contactor moves valve Open and Close contactor moves valve Closed.
DANGER: Improper power voltage phasing eliminates protection of both geared limit switch and torque switch, risking valve damage.
TO SET OPEN LIMIT SWITCH (LSO)
1. Open valve — During handwheel operation note direction of rotation of LSO Adjusting Shaft (1) fig. 1. After the valve is fully Open, Close it three handwheel turns to allow for coast.
2. Disengage spring loaded spur
gear — Push Disengage Shaft (2) in fig. 2 down, then rotate 90° so that shaft is captured in down position.
This disengages limit switch gears from the spring loaded gear pinion assembly.
3. Line up LSO indicator: If switch rotor does not line with arrows on instruction plate as shown in fig. 3, rotate screwdriver in same direction noted in Step 1 until switch just rotates. If indicators line up as shown in fig. 3a, rotate screwdriver in the opposite direction until switch just rotates, then slowly reverse direction to match fig. 3a.
4. Re-engage spring loaded spur gear by turning Disengage Shaft (2) fig. 2.
Disengage Shaft (2) will rise.
5. IMPORTANT: To insure that spur gears have engaged properly, lightly jiggle all adjusting shafts
(1) with screwdriver back and forth; proper engagement has been made if all shafts will not turn. If all shafts do not lock in place, the limit switch setting will be lost when valve is moved.

Fig. 3a
(1) fig. 2
(2)
NOTE: Since many turns may be required to set limit switches, it may be convenient to use a reversible variable speed drill to rotate
Adjusting Shaft (1) instead of screwdriver.
Limit Switch Gear Box is gear driven by the gear limit pinion assembly. The gear limit pinion is driven by the actuator output worm and is always mechanucally in step with valve position.
N is the total number of turns of spring loaded gear limit pinion assembly for full valve stroke.
TO SET CLOSE LIMIT SWITCH
(LSC)
1. Close valve, using handwheel.
During handwheel operation note direction of LSC adjusting shaft. After valve is fully Closed, Open it several handwheel turns to allow for coasting.
2. Repeat steps 2 through 5 of LSO setting instructions with screwdriver in LSC cavity.
TO SET INTERMEDIATE SWITCH
(LSA OR LSB)
1. Open Valve to desired position, then repeat steps 2 through 5 of LSO.
TORQUE SEATED VALVES
If valve is a torque seating valve, and the geared limit contacts are used for pilot light indication only, the LSC switch should be set several handwheel turns ahead of torque switch contact action.
This gives proper valve position Pilot
Lamp indication in spite of minor position variations which might occur due to torque seating.

TORQUE SWITCH TSC AND TSO SETTING
Description
EIM Torque Switch senses mechanical over load in Close (TSC) or Open (TSO) direction. Worm is supported with bi-directional disc spring stack.
As worm and gear torque increases, the worm moves axially against spring allowing Torque
Limit Gear Assembly to rotate Part No. 1050,
Torque Switch.
Part Number 1050 has N.C. contact for (LSC) and (LSO). Part number 1050-1, in addition to
N.C. also provides a N.O. contact
EIM E1195
Adjust With Screwdriver
The only tool required for torque adjustment is a screwdriver. To change setting: push screwdriver down about 1/16" and rotate.
Torque Switch Calibration
Approximate
Torque Spring Chart
See EIM supplied specification sheet for approximate torque spring settings.
Manufacturing tolerances affect the torque at a specific torque switch setting. If exact torque curve is required; at an additional charge, EIM will test and plot curve for specific actuator.
To Set CLOSE Torque Switch (TSC) a) Close valve using handwheel.
Set valve to the desired torque.
Observe rotating dial for number that corresponds to desired
Valve Close Torque.
b) Insert screwdriver in slot of TSC dial. Press down to disengage and turn the arrow to the setting determined in a). Release at this point and it will re-engage and remain set automatically.
c) Back the valve away from Close position and reseat by handwheel to verify the trip point is at desired setting. The trip point of switch is distinctive as it makes or breaks contact.
d) DANGER:
REVERSE VOLTAGE PHAS-
ING REMOVES TORQUE
SWITCH PROTECTION FROM
REVERSING CONTACTOR.
VALVE DAMAGE COULD
OCCUR. If phasing has not been checked, do so before proceeding. Back valve away from Close position with handwheel and test electrically, using
Close controls. Readjust as required.
To Set OPEN Torque Switch (TSO) a) Follow the procedure as for the
TSC in open position.
Switch Rotation Limit
Torque Switch adjustment rotation may be limited. Remove switch cover to expose anti-rotation pins at Open and Close positions. Remove pin from position 10 and insert into desired number. Torque may be roughly estimated from Table on EIM Spec Sheet or determined by production or actual field test.

MDPI & POTENTIOMETER GEAR BOX P/N 1030 EIM E1195
Description
Mechanical Dial Position Indicator,
MDPI, Part No. 1030 is a precision assembly of gears, shafts, bearings and slip-clutch designed to drive Position
Indication arrow and/or Potentiometers.
The MDPI is geared to actuator mechanism and is “in-step” with the valve position at all times, whether operation is by motor or handwheel.
MDPI is mounted to the top of Limit
Switches; this allows addition of potentiometer to valve actuators that are determined later to require process control. Top mounting allows for moving valve actuator from one valve to another.
N Number
N is the total number of Gear Limit
Pinion turns for full valve travel. Pinion is Part No. (17) on assembly drawings.
Calibration
MDPI & POT Drive is calibrated after
LSC and LSO are properly set. See p.4.
MDPI and POT
Move valve to Close position. Manually rotate MDPI arrow to indicate Close.
Calibration is complete. Open valve to check that MDPI arrow goes to Open, indicating that N is correct for full valve travel. Potentiometer, if included, has also been calibrated. Mechanical dial travel is 270°. Approximately 5% of total resistance is left on each end of Pot for total valve travel.
10-Turn Pot is driven 8.89 turns; 5% resistance of element is left on each end of Pot for total travel. This may be adjusted to a specific minimum resistance value at Open or Close by using a screwdriver in slot on 10 turn pot.
Potentiometer Only
Potentiometer shaft is rotated by grasping flats of P/N 1031 slip-clutch and turning to desired resistance. 1-turn
Pot is rotated 270° by P/N 1030 gear box.
PART NO. 1030 — CHANGE
