MCSE Series Operating Instructions
• Maintain compressed air quality, i.e., filtration, pressure regulation, lubrication.
• Avoid compressor oils that can cause valve seals to swell, soften, or otherwise
deteriorate.
• Conduct leakage tests of the load holding system, including the connecting lines,
fittings, and actuator seals, on commissioning and periodically during use.
• Operate within prescribed temperature limits.
• Install the valve such that the normal stroke travel of the valve elements are
perpendicular to the main direction of machine vibration and/or mechanical shock.
• Avoid external magnetic fields.
• Do not plug the valve exhaust port.
• Use only high-flow, non-clogging silencers, with similar or higher specifications as
ROSS
silencers.

2.1.3. Diagnostic Coverage
A diagnostic coverage of 99% is achievable through appropriate integration of the
MCSE Series valve into the safety control system.
2.1.4. Improper Use
Risk of Injury!
Misuse may result in injury or damage.
f The product must be used exclusively as intended.
The following applications are prohibited:
•
Use outdoors
•
Use in non-industrial applications/residential areas
•
Use outside of the product limits defined in the technical data
•
Unauthorized modifications
•
Use as a press safety valve to control a clutch or brake
•
Operation with a low demand rate (low demand mode) according to IEC 61508
•
Bypassing the safety function or diagnostics
•
Use in reverse operation (reversal of supply and exhaust air, reversal of output
and supply)
ROSS CONTROLS is not liable for any damages resulting from improper use. The
user alone bears the risks of improper use of the product.
2.2. Responsibilities of the System Owner
•
Observe the information on assembly and operating conditions listed in the
operating instructions or the data sheet.
•
Comply with the further requirements of ISO 13849 (e.g., CCF, DC, PLr, software)
if you intend to use the product in higher categories (2, 3, or 4).
•
Make sure that the maximum number of switching cycles (B
life T
is not exceeded. If the expected number of switching cycles for a component
m
exceeds the B
value during its period of use, suitable replacement intervals have
10D
to be specified.
•
Switch the valve at least once a month to ensure its proper operation.
•
Make sure that the fundamental and proven safety principles in accordance with
ISO 13849 for implementation and operation of the component are complied with.
•
Make sure that the permissible positive and negative test pulses for feedback-
free operation of the pneumatic devices are observed (see chapter 12 "Technical
Specifications").
2.3. Safety Instructions
•
When implementing surge suppression measures, be sure to check whether or
not this extends the valve shut off response time which could extend the machine
stopping time.
•
In case of high levels of machine vibration, use appropriate vibration-reducing
elements when installing the valve.
•
Supply the proper voltage as overvoltage situations can result in solenoid burnout.
•
Make sure that the silencer's flow capacity is not restricted as this could affect
system performance.
•
If required, replace the silencer exclusively with a corresponding ROSS model.

6. Service and Maintenance
f The MCSE valve is not repairable. Do not attempt to adjust or repair the valve.
In case of technical problems or a required service, please contact your local
ROSS representative. If used properly, the MCSE Series double valves will not
require maintenance. Unless otherwise required, ROSS
a functional test at least once a month (see 8.1 Test Procedure).
7. Assembly and Installation
Risk of injury due to installation while pressurized or with live parts!
Installation while pressurized or with electrical power switched on can result in
injuries due to sudden pressure build-up or electric shock.
f De-energize and de-pressurize the relevant system parts before installing the valves.
f Secure the system to prevent it being switched back on again.
ATTENTION
Destruction of components!
Chemical substances can damage the surface, the markings and the seals of the device.
f Install the valve such that it is protected against the effects of chemicals.
Damage to the device through storage at incorrect temperatures!
The storage temperature represents the permissible ambient temperature and de-
pends on the type of valve in question.
f Observe the temperature information in chapter 12 "Technical Specifications."
7.1. Mechanical Installation
Prepare for assembly as follows:
1. Stop system operation and protect it against being switched on.
2. Return all suspended loads to a statically secure position or remove them from
the system.
3. If required, exhaust stored compressed air from system parts in the immediate work area.
4. Make sure the relevant section of the system is not under pressure or voltage and
protect it from being switched on.
5. Secure self-turning or other movable system parts before starting assembly.
6. Let the MCSE safety valve acclimatize itself for several hours before installation,
otherwise water may condense in the housing.
Mount the Valve
To mount a single valve – See page 2.
To mount the valve as part of a maintenance unit – See page 2.
The valve must be mounted on both sides with one mounting element each on the
mounting surface.
7.2. Pneumatic Installation
Mount the pressure sensor or pressure gauge (optional)
A pressure gauge or electronic pressure sensor can be connected to the thread
connection(see page 3) once the blanking plug has been removed.
Observe the mounting instructions enclosed with the components.
7.3. Pneumatic and Electrical Connections
Pneumatic Connections
Requirement: The supply pressure must always be between 29 psig (2 bar) and up to
145 psig (10 bar).
Note: The correct function of the MSCE safety valve is not guaranteed if the supply
pressure is lower than 29 psig (2 bar) and up to 145 psig (10 bar).
1. Connect the pressure line for the supply pressure to connection 1 (1, IN).
2. Connect the operating line to connection 2 (2, OUT).
Electrical Connections
1. Connect the supply voltage to plug XPS, the signal output, and, if applicable, start
signal X2.
The assignment of the XPS plug is the same for all versions.
The contacts on the XPS plug, M12 male have the following pin assignment:
