3/2 RSe Series Safe Exhaust Double Valves Integration Guide
Introduction
ROSS Controls offers a variety of safety valves for use in various safety functions such as safe exhaust, safe cylinder return, and safe
load holding/stop. This document focuses specifically on ROSS Controls’ 3/2 RSe Series valves that are used for safe pneumatic exhaust
functions and utilize magnetic proximity sensors (PNP) to provide feedback to a safety control system for external monitoring.
Pulse Testing
In dual channel safety circuits, pulse testing is a method utilized to detect fault conditions that, otherwise, may be undetected. Pulse testing
of the solenoids is required in dual channel circuits in order to reach Performance Level e (PL e). However, pulse testing of the feedback
sensors is not required. Pulse testing of the solenoids will not affect the performance of the ROSS 3/2 RSe valve.
There are two methods of pulse testing outputs. The most common method is to use the native pulse testing instruction embedded by
the manufacturer in Safety PLCs and Safety Relays. The other method is to use custom programming code generated by the user. We
recommend the use of native pulse testing instructions of the respective manufacturers’ Safety PLCs or Safety Relays because these
instructions are fixed and cannot be tampered with. These instructions typically have a pulse period (cycle) of 400 ms to 600 ms and a
pulse width of 0.4 ms to 0.8 ms. Pulse testing the outputs to the solenoids on the RSe valve at this frequency and duration does not affect
the performance of the valve but does provide a method to monitor for the occurrence of wiring faults in the output portion of the safety
circuit controlling the valve solenoids.
Exhaust Times and Faulted Flow Rates
When designing a safety circuit, the machine stopping time is a critical factor that determines the placement of guarding solutions. One
factor in safe distance calculations is the exhaust time of the valve that is responsible for isolating and dumping the pneumatic energy from
the machine. The faster your valve exhausts, the quicker the machine can stop and the closer your safety devices may be placed to the
hazardous area. This can improve overall operating efficiency, and possibly allow the footprint of the machine to be smaller.
Even more important than exhaust time is the “Faulted exhaust flow rate.” Faulted exhaust flow rate is the exhaust rate of the valve in
its worst state. Double valves (redundant valve systems used for safety applications) will not exhaust quite as quickly when there is an
internal fault condition in the valve, such as when one of the redundant valve components is actuated and the other one is not actuated.
For this reason, double valves used in safety circuits should always be sized using faulted flow rates as the worst case condition.
The chart below shows the RSe valve’s faulted exhaust flow times at various downstream volumes and operating pressures.

Pilot Supply Conversion
The RSe Series valve comes from the factory configured for internal pilot supply, which sources pilot supply air pressure internally
from port 1 in the valve sub-base. However, the valve can be converted in the field to operate with external pilot supply through
the EPS port in the valve sub-base. When this conversion to external pilot supply is made, the valve solenoid pilots will get their
supply air from a source that is independent of the supply line connected to Port 1.
External pilot supply is typically used in applications where the normal supply pressure may be lower than the minimum operating
pressure of the valve (45 psig (3 bar)).
In order to convert the RSe valve to external pilot supply:
A. Shut off and exhaust all pressure from the system and disconnect all electrical power from the valve.
B. Remove the valve from the sub-base (4 screws). See photo below.
C. Remove the set screw from the external pilot supply port in the top of the base. See figures below.
D. Install the set screw in the internal pilot supply port in the top of the sub-base (max. torque 49 in-lbs (5.5 Nm). See figures below.
E. Install an external pilot supply line into the EPS port in the side of the sub-base. The source for this external pilot supply should
supply a constant supply of air with pressure greater than or equal to the supply pressure in Port 1; 45 psig (3 bar) minimum.
F. Re-install the valve on the sub-base (4 screws - max. torque 49 in-lbs (5.5 Nm)). See photo below.

Operation & Monitoring Requirements for 3/2 RSe Series Safe Exhaust Valves
The intent of this document is to provide guidance on how to operate and monitor the 3/2 RSe valve for safe operation. A test
procedure is also provided for verification and validation of the user’s external safety control monitoring system.
Valve Operation
The 3/2 RSe valve is a redundant safe exhaust (dump) valve. Its function is that of a 3/2, normally closed, single-solenoid valve.
However, because the valve is redundant it has two operating solenoids that must be operated simultaneously in order to actuate the
valve. In addition each valve element has a single, proximity sensor that is wired as a PNP type sensor for position sensing.
Actuating the valve will supply pressure from port 1 (supply) to port 2 (outlet) and close port 3 (exhaust).
De-actuating the valve will close port 1 (supply) and open port 2 (outlet) to port 3 (exhaust). De-actuation of the valve is accomplished
by turning off both solenoids simultaneously.
Normal operation occurs when both sets of valve internals shift within 250 msec of the change of the solenoid signals. For example,
when both solenoids are signaled to energize, we would expect both proximity sensors to turn off within 250 msec of application of
the solenoid signals. Each sensor only reacts to its associated solenoid.
In the event of a valve fault where one of the redundant valve components does not operate normally, as commanded, the valve will
perform its safety function which is to shut off supply and exhaust downstream pressure to atmosphere.
The fault should be latched in by the safety monitoring system until a reset is performed.
Failure of the valve to shift normally leads to a fault in the 3/2 RSe valve. This could happen for a variety of reasons, such as:
• Compromised piston seals
• Main valve elements experiencing a switching delay due to dirt, debris or resinous oil
• Insufficient electrical signals to valve solenoids; suitable voltage not available
• Receipt of signals at solenoids not synchronous
• Pilot valves experiencing a switching delay due to damaged components, dirt, debris or resinous oil
• Excessive water build-up in the valve

3/2 RSe Series Safe Exhaust Double Valves Integration Guide
Feedback Monitoring (General)
The 3/2 RSe valve is equipped with feedback proximity sensors that must be monitored by the user’s external safety control &
monitoring system to detect any fault condition within the valve. Sensor feedback should always be opposite the solenoid actuating
signals. In other words, when the solenoids are energized, the sensor outputs should be off and when the solenoids are de-
energized, the sensor outputs should be on.
WARNING: It is possible to operate at a cycle rate that could result in non-monitored operation. To prevent exceeding this rate,
ensure that the valve is de-actuated (both sensor outputs should be on) before attempting to energize the solenoids. Likewise,
ensure that the valve is actuated (both sensor outputs should be off) before attempting to de-energize the solenoids.
NOTE: In the event of a stop signal from any safety system input, the safety system should immediately shut off the safety controller
outputs to the valve solenoids (as required by the application) regardless of the condition of the feedback sensors.
Refer to EN ISO13849-1 for Cat 3 vs Cat 4 monitoring.
Automatic RESET is not recommended by ROSS.

Actuation Fault Monitoring
Actuation fault monitoring should check for actuation of both valves within 250 msec of the actuation signal. After the safety control
system outputs provide simultaneous actuation signals to both solenoids, both sensor outputs should switch off within 250 msec.
If both sensors have not changed state within the 250 msec timeframe, this should be registered as a valve fault.

De-Actuation Fault Monitoring
De-Actuation fault monitoring should check for de-actuation of both valves within 250 msec of the removal of the actuation signal.
After the safety control system simultaneously removes the actuation signals from both solenoids, both sensor outputs should
switch on within 250 msec. If both sensors have not changed state within the 250 msec timeframe, this should be registered
as a valve fault.

Loss of Supply Pressure While Actuated
The condition of loss of supply pressure to port 1 while the valve is actuated must be detected by the safety control monitoring system.
NOTE: This is only possible when using INTERNAL pilot supply, unless an additional pressure switch or transducer is added
upstream of the valve in port 1.
Loss of supply pressure while actuated should cause both valves to de-actuate due to lack of pilot pressure; thus, causing both
sensors to switch on even though the solenoids are still energized. Therefore, this fault can be detected when the solenoids
are energized, and one or both sensors go from off (sensing the actuated position) to on (not sensing the actuated position).
NOTE: No additional ladder logic is required for Loss of Supply Pressure While Actuated because this fault is detected by the
Actuation Fault Monitoring logic.
No Supply Pressure Applied Before Actuation
Monitoring of supply pressure may also be utilized if deemed beneficial for the application but is not required. If you choose to
detect this condition it would require the addition of an upstream pressure switch or transducer. The condition of the pressure
switch or transducer should be monitored to prevent actuation of the valve when supply pressure is insufficient.
NOTE: No ladder logic example provided for additional equipment.
Valve Fault & Safety System Reset
Any detected fault in the valve system should cause the safety control system to de-actuate the valve by removing power from both
solenoids. Any fault should be latched in by the safety monitoring system until a reset is performed. A reset of the safety control
system should only be possible after the valve sensors indicate that the valve is in the de-actuated state (both sensor outputs are
on). The valve solenoids must be de-energized during Reset.

NOTE 1: This validation test procedure should only be performed with a 3/2 RSe valve that is known to be functioning properly. If basic valve function is in
question please refer to Section 8 of the Product Operating Instructions for the Valve Test Procedure.
NOTE 2: These procedures require fault simulation. It will be necessary to induce faults electrically by disabling a different solenoid or sensor at different times.
This will be most easily done by disconnecting solenoid or sensor cables at the valve.
NOTE 3: Port 2 should be connected to a gauge or pressure sensor teed into the line.
NOTE 4: Supply pressure will need to be supplied to inlet port 1.
NOTE 5: This procedure pertains to internal pilot conguration only.
NOTE 6: “-“ indicates no change from previous step.
NOTE 7: Actuate Signal is the signal to switch on the solenoids either from a physical input switch or a software signal.

AS SET FORTH HEREIN.
PRE-INSTALLATION or SERVICE
1. Before servicing a valve or other pneumatic component, be sure all sources of
energy are turned off, the entire pneumatic system is shut down and exhausted,
and all power sources are locked out (ref: OSHA 1910.147, EN 1037).
2. All ROSS Group Products, including service kits and parts, should be installed
and/or serviced only by persons having training and experience with pneumatic
equipment. Because any product can be tampered with and/or need servicing
after installation, persons responsible for the safety of others or the care of
equipment must check ROSS Group Products on a regular basis and perform
all necessary maintenance to ensure safe operating conditions.
3. All applicable instructions should be read and complied with before using
any uid power system to prevent harm to persons or equipment. In addition,
overhauled or serviced valves must be functionally tested prior to installation
and use. If you have any questions, call your nearest ROSS Group location.
4. Each ROSS Group Product should be used within its specication limits. In

FILTRATION and LUBRICATION
1. Dirt, scale, moisture, etc., are present in virtually every air system. Although
some valves are more tolerant of these contaminants than others, best
performance will be realized if a lter is installed to clean the air supply, thus
preventing contaminants from interfering with the proper performance of the
equipment. The ROSS Group recommends a lter with a 5-micron rating for
normal applications.
2. All standard ROSS Group lters and lubricators with polycarbonate plastic
bowls are designed for compressed air applications only. Use the metal bowl
guard, where provided, to minimize danger from high pressure fragmentation in
the event of bowl failure. Do not expose these products to certain uids, such as
alcohol or liqueed petroleum gas, as they can cause bowls to rupture, creating
a combustible condition and hazardous leakage. Immediately replace crazed,
cracked, or deteriorated bowls.
3. Only use lubricants which are compatible with materials used in the valves and
other components in the system. Normally, compatible lubricants are petroleum
base oils with oxidation inhibitors, an aniline point between 180°F (82°C) and
220°F (104°C), and an ISO 32, or lighter, viscosity. Avoid oils with phosphate
type additives which can harm polyurethane components, potentially leading to
valve failure which risks personal injury, and/or damage to property.
WARNINGS:
Failure to follow these instructions can result in personal injury and/or
property damage.
AVOID INTAKE/EXHAUST RESTRICTION
1. Do not restrict air ow in the supply line. To do so could reduce the pressure
of the supply air below minimum requirements for the valve and thereby causing
erratic action.
2. Do not restrict a valve's exhaust port as this can adversely affect its operation.
Exhaust silencers must be resistant to clogging and must have ow capacities
at least as great as the exhaust capacities of the valves. Contamination of the
silencer can result in reduced ow and increased back pressure.
WARNINGS: Failure to follow these instructions can result in personal injury
and/or property damage.
SAFETY APPLICATIONS
1. Mechanical Power Presses and other potentially hazardous machinery using a
pneumatically controlled clutch and brake mechanism must use a press control
double valve with a monitoring device. A double valve without a self-contained
monitoring device should be used only in conjunction with a control system
which assures monitoring of the valve. All double valve installations involving
hazardous applications should incorporate a monitoring system which inhibits
further operation of the valve and machine in the event of a failure within the
valve mechanism.
2. Safe Exhaust (dump) valves without a self-contained monitoring device should
be used only in conjunction with a control system which assures monitoring of
the valve. All Safe Exhaust valve installations should incorporate a monitoring
system which inhibits further operation of the valve and machine in the event of
a failure within the valve mechanism.
3. Per specications and regulations, the ROSS L-O-X®and L-O-X®with EEZ-ON®,
N06 and N16 Series operation products are dened as energy isolation devices,
NOT AS EMERGENCY STOP DEVICES.
WARNINGS:
Failure to follow these instructions can result in personal injury and/or property
damage.
