What the Module Does

Using A ControlLogix Hydraulic Servo Module in the ControlLogix System

Certifying Agency Approvals 11 Preventing Electrostatic Discharge 12 Removal and Insertion Under Power 12

THe 1756-HYD02 module is typically used for accurate positioning and control of a hydraulic cylinder. The module can be wired to a linear displacement transducer (LDT) for feedback and a proportional or servo valve for control of a hydraulic axis and connects to a hydraulic system to close a high-speed position loop. Each Logix controller can support up to 16 1756-HYD02 modules. Each 1756-HYD02 module can control up to two axes.

The 1756-HYD02 module monitors the position feedback via the linear displacement transducer (LDT) input and generates an analog command reference for the valve to make sure that the actuator (cylinder) follows the profile. The 1756-HYD02 module closes the position loop at a programmed rate using position feedback as the input and produces a +/-10V analog output velocity command.

The module is programmed with motion instructions in the RSLogix 5000 programming software and must be in the same chassis as the ControlLogix controller that controls the module. If you distribute motion control that uses the 1756-HYD02 module across different locations, place a ControlLogix controller in each chassis that has a 1756-HYD02 module. In this case, use a 1756-SYNCH module to synchronize motion between the multiple chassis.

Transducers connected to the 1756-HYD02 must accept external interrogation signals. In this case, the transducer generates its position information each time that it receives an interrogation pulse. Do not use transducers configured for internal interrogation because they will not be properly synchronized to the module.

Chapter Summary and What’s Next

WARNING

Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

We do not recommend removing and inserting the 1756-HYD02 module while under power if the servo loop is closed. Make sure the servo loop is open, that is, flashing green feedback indicator, before removing or inserting the module under power.

In this chapter, you read a description of the 1756-HYD02 module. Chapter 2 describes

Installing the 1756-HYD02 Module

When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

However, as stated on the previous page, the 1756-HYD02 module should not be pulled under power, nor should a powered RTB be removed, in a Class I Division 2 environment.

Keying the Removable Terminal Block

Key the RTB to prevent inadvertently connecting the incorrect RTB to your module. When the RTB mounts onto the module, keyed positions match up. For example, if you place a U-shaped keying band in position #4 on the module, you cannot place a wedge-shaped tab in #4 on the RTB or your RTB will not mount on the module.

Use a unique keying pattern for each slot in the chassis.

1. Insert the U-shaped band with the long side near the terminals.

2. Push the band onto the module until it snaps in place.

Chapter 2 Installing the 1756-HYD02 Module

Choosing the Extended-Depth Housing

There are two housing options you must consider when wiring your ControlLogix Hydraulic Servo module. When you order an RTB for your I/O module, you receive a standard-depth housing with the RTB. If your application uses heavy gauge wiring, you can order an extended-depth housing. This housing does not come with an RTB.

You can use one of the housings listed below:

This housing: should be used with this RTB: and allows up to this

capacity of wires:

1756-TBCH Cage clamp 336 sq. mm 1756-TBS6H Spring clamp 1756-TBE Any RTB using heavy gauge wiring 628 sq. mm

The figure below shows the difference, in terms of capacity, between the housing options.

IMPORTANT

The housings shown are used with a spring clamp RTB, but the capacity for each remains the same regardless of RTB type.

Maximum Area = 336 sq. mm

36 - 18AWG wires

23 - 14AWG wires

Standard-Depth Housing Extended-Depth Housing

IMPORTANT

The housings use the following maximum areas:

• standard-depth housing maximum area = 336 sq. mm

• extended-depth housing maximum area = 628 sq. mm

Maximum Area = 628 sq. mm

Suggestions for Using the Extended-Depth Housing

12.7mm (0.5in)

TIP

Consider the following when deciding to use an extended-depth housing on your I/O module. It is recommended you use the 1756-TBE when:

• using >36 18AWG wires

• using >23 14AWG wires

Cabinet Size Considerations With the Extended-Depth Housing

When you use an extended-depth housing (1756-TBE), the module depth is increased. Figure shows the difference, in terms of depth, between a module using a standard-depth housing and one using an extended-depth housing.

Chapter 2 Installing the 1756-HYD02 Module

Installing the Removable Terminal Block

Install the RTB onto the module to connect wiring.

ATTENTION

Shock hazard exists. If the RTB is installed onto the module

while the field-side power is applied, the RTB will be electrically live. Do not touch the RTB’s terminals. Failure to observe this caution may cause personal injury.

The RTB is designed to support Removal and Insertion Under Power (RIUP). However, when you remove or insert an RTB with field-side power applied, unintended machine motion or loss of process control can occur. Exercise extreme caution when using this feature. It is recommended that field-side power be removed before installing the RTB onto the module.

Before installing the RTB, make certain:

• field-side wiring of the RTB has been completed.

• the RTB housing is snapped into place on the RTB.

• the RTB housing door is closed.

• the locking tab at the top of the module is unlocked.

1. Align the top, bottom and left side guides of the RTB with the guides on the module.

Removing the Removable Terminal Block

If you need to remove the module from the chassis, you must first remove the RTB from the module.

ATTENTION

Shock hazard exists. If the RTB is removed from the module

while the field-side power is applied, the module will be electrically live. Do not touch the RTB’s terminals. Failure to observe this caution may cause personal injury.

1. Unlock the locking tab at the top of the module.

2. Open the RTB door using the bottom tab.

3. Hold the spot marked PULL HERE and pull the RTB off the module.

IMPORTANT

Do not wrap your fingers around the entire door. A shock hazard exists.
