BRAY Series 52 Valve Status Monitor Operation and Maintenance Manual

Introduction

Note: The following information is intended to assist individuals with the use and support of the Bray S52 Valve Status Monitors.

The Series 52 Valve Status Monitor has been designed to provide valve position indication. The 2N1TM ProxSensor is available in several con-

gurations:

• DC Version 10-30VDC PNP (Sourcing)

• DC Version 10-30VDC NPN (Sinking)

• DC NAMUR Intrinsically Safe Version

(to be used with IS Barrier)

• AC Version 20-250VAC, 50-60Hz

• Fieldbus capable Versions

1. AS-i (Actuator Sensor Interface)

2. DeviceNet

3. PROFIBUS DP (Process Fieldbus Decentralized Peripherals)

Each of these congurations will be covered in

more detail on the pages that follow. Additionally, examples of how to apply some of these products will be given.

All Bray S52 Valve Status Monitors utilize solid state switches. Although the solid state switch performs the same function as a conventional mechanical switch, there are differences in the way solid state switches operate.

NOTICE

It is very important for the user to pay close

attention to the exact specications of their

sensor in order to avoid damaging the unit.

Solid state switches have current restrictions imposed by the semi conducting materials used to form the sensor. These current limitations have to be accounted for during setup. Unlike mechanical switches, which can normally handle several

amperes of current owing through them, solid

state switches are generally rated for half an ampere or less.

NOTICE

The Parameters of the S52 must be compatible with the application

When working with the S52, several parameters

must be considered. A few of which (with signicant importance) are listed here: operating volt-

age, maximum switching current, output voltage drop, and residual current. Using an S52 outside of these parameter limits can cause damage to the unit and void factory warranty.

Operating voltage is the amount of voltage necessary for the sensor to operate. The maximum switching current is the largest amount of current that the sensor’s solid state electronics can

have owing through them in the On-State (when

the target is in proximity of the sensor). During commissioning, it is up to the user to correctly apply the sensor to their control system in order to

limit the current owing through the device. This

is done through the use of a load; all the wiring diagrams associated with the S52s specify where this load needs to be placed in the circuit. Common control systems utilize a digital input card to monitor devices like the S52; these cards have loads (parameter usually referred to as “input impedance”) – it is the responsibility of the user to

ensure that this load is sufciently sized to limit the current owing through the S52 below the

maximum switching current, yet above the OnState input current minimum of their monitoring device. We will cover an example of this on page 14-15.

Output voltage drop is dened as the amount of

voltage that will drop across the solid state switch. This voltage drop will often vary with the amount

of current owing through the sensor and the load.

BRAY Series 52 Valve Status Monitor Operation and Maintenance Manual

This drop in voltage becomes paramount when connecting several valve status monitors in series, each unit will have a voltage drop across it – adding each subsequent drop and subtracting from the supply voltage yields the resulting voltage at the end of the series connection. The user needs to ensure that the supply voltage is large enough so that the resulting voltage after all the drops is above the min. operating voltage of the last S52 in the series connection. Sensors located a great distance from the load require consideration as well, as a general rule, every 1000 ft. of wire will have

a resistance of 10Ω (see electrical code references for the resistance value of specic wire sizes), it is

important for the customer to ensure that the distance between the S52 and the control panel is not long enough to cause the voltage drop to fall below the minimum operating voltage of the sensor.

Residual current is often referred to as leakage current. In the “Off” state (target is NOT in proximity of the sensor) the sensor draws a small

amount of current in order to power the device’s electronics. This is necessary for the device to sense the target at any point in time when the supply voltage is applied. It is important that this residual current is below the maximum Off-State current rating of the control system.

Target Mounting

All congurations of the S52 are offered with two

types of targets; adjustable and non-adjustable. Standard S52 (AC, DC, and DC Intrinsically Safe units) utilize inductive proximity sensing technolo-

gy to provide valve position indication; the eldbus

capable versions utilize hall effect sensing technology to accomplish the same objective. When ap-

plying eldbus capable S52s, the same targets are

used; however, small magnets are located in the small chambers behind the metal inserts on the sides of the targets.

Adjustable Target Mounting

The adjustable versions are for customers that want the exibility to position their indication limits outside

of the standard 0 to 90°. The components that come in the adjustable target kit are displayed in Figure 1. Figure 2 shows the components of the High Visibility Indicator Kit and the adjustable target kit.

BRAY Series 52 Valve Status Monitor Operation and Maintenance Manual

The steps required to set up the adjustable target for your S52 2N1 Valve Status Monitor:

Step 1: Place the base on top of your pneumatic actuator’s output pinion.

Step 3: Place the top piece so that the metal target will be directly in front of the top switch (labeled

1) on the S52 when the actuator rotates to it’s opposite end of travel position. If you have a high visibility indicator kit, jump to step 5 - otherwise proceed to step 4.

Step 2: Place the middle piece on top of the base so that the metal target is in front of where the bottom switch (labeled 2) of the S52 will be located.

Step 4: Place the yellow pointer in your desired

orientation and tighten the mounting screw. Note:

Units assembled at the factory will have yellow pointers in line with valve discs.

Step 5: Mount the high visibility beacon on top of the target to display ‘Open’ and ‘Closed’ according to your actuator/valve mounting orientation.

Step 6: Tighten the mounting screw to ensure that your indicator and target are secured to the pinion of the actuator. Note: damage to the indicator can

result from over tightening the screw.

BRAY Series 52 Valve Status Monitor Operation and Maintenance Manual

Step 7: Place the S52 on the actuator, aligning the holes in the sensor with the mounting holes of the actuator. Insert the cover over the indicator and align the mounting holes of the cover with those of the sensor. Use the longer mounting bolts supplied with your kit and tighten the cover and sensor to the actuator.

Non-Adjustable Target Mounting

The S52 Valve Status Monitor is offered with a non-adjustable target. The non-adjustable target is a one piece puck style target with metal inserts offset by 90°. The yellow pointer however is adjustable and can be positioned however you require; when the unit is mounted at the factory the pointer will be in line with the

valve disc. All components of the non-adjustable kit are shown below in Figure 3. The procedure for mount-

ing the non-adjustable target is described on the next page. Note: when conguring this target with your

input monitoring device pay close attention to metal insert position versus sensor position as your actuator rotates from open to close.

Figure 3: Non-Adjustable Target with pointer.

Figure 4: Non-adjustable Target mounting

Mounting of the non-adjustable target:

Insert the target on the pinion of the pneumatic actuator. Based on what position your pinion/actuator is in, one of the metal inserts of the target will be directly in front of switch ‘1’ or switch ‘2’ on your sensor. When your quarter turn actuator rotates 90° to its opposite travel limit, the other metal insert of the target will be directly in front of switch ‘2’ or switch ‘1’, respectively. Position your actuator to yield your desired indication results.

BRAY Series 52 Valve Status Monitor Operation and Maintenance Manual

The Standard S52 (non eldbus capable versions) are offered with two types of connections; the DC versions are offered with a 4-pin M12 connection, and the AC versions are offered with a 5-pin 7/8” con-

nection. Both types are pictured below:

From this information, and the DC PNP S52 specications on page 7, you should be able to determine

that these two devices are compatible.

• The operating voltage of the DC S52 (specied as: 10-30VDC) is within the acceptable On-State Input Voltage Min. and Max. range of the Input Module (specied as: 10VDC to 30 VDC @86°F/26.4Vdc

@140°F).

• The residual Off-state Current of the DC S52 (specied as: 20 μA) is below the Off-State Current Max. of the Input Card (specied as: 1.5mA). Note: this means that the leakage current of the S52 will not

cause false readings.

• The Nominal Impedance of the Input Card (specied as: 3kΩ) is sufcient enough to limit the current owing through the proximity switch below its Max. Switching Current (specied as: 200mA).

Ohm’s Law: V = IR (V = Voltage, I = Current, R = Resistance*) 24VDC = I x 3 KΩ

24/3000 = .008 A or 8 mA

This value is the amount of current that will ow through the S52 in the On-State (when the target is

in proximity of the sensor). This value, 8 mA, is below the Max. Switching Current of the S52 (current exceeding 200mA can damage the device) and above the Min. On-State Input Current of the input

module (specied as: 2mA). *Note: Resistance in this case is referred to as Input Impedance

Once you have determined the compatibility of the two devices; you can wire the two devices together using their appropriate wiring diagrams. The diagram in Figure 5 below shows you how to do this correctly.

Note: Each proximity switch in the S52 will require a separate input into the PLC card; thus, (1) S52 will utilize (2) inputs into the PLC Input Module. One input for ‘Valve Open’ indication and one for ‘Valve

Close’ indication. Because this specic input module only has 6 inputs, three S52s can be wired into this device. The number of necessary modules grows quite rapidly when you have several devices in use; this is why eldbus capable versions can be so cost effective, for more information please see the eldbus ap-

plication example.

Application Example #2 (AS-i S52)

Customer has an AS-i (Actuator Sensor Interface) controller with an AS-i approved 24VDC power sup-

ply. Once your customer has the conguration software (usually provided with the controller) they can scan the bus and congure any AS-i device connected. Up to 62 devices can be connected to one con-

troller (V2.1 or 3), in applications requiring several valve status monitors, cost is greatly reduced when only one single module can control 62 devices versus having to purchase a PLC input module for every three to four S52s that you have.

1) Bray S52 is connected to the AS-i BUS and is located at address 12.

2) By selecting the device at address

12, a conguration window allows

you to modify the device address, check input state, and test the output.

3) Input 1 is shown in the ‘On’ State, Input 0 is ‘Off’, and the Output to the solenoid is not energized.
