MCSE Series Operating Instructions
Additional help for malfunctions can be found in the following table:
If you are unable to troubleshoot the MCSE safety valve malfunction yourself:
• Disassemble the MCSE safety valve as described in chapter 10 "Disassembly and
Exchange" and send it to ROSS CONTROLS. You can find the address on the back
of the operating instructions.

Remedy
Increase the power supply. Use a cable
with a larger diameter
Reduce the power supply
Check the wiring and correct if necessary
Select a supply voltage according to the
technical data
Check the compressed air supply. Change
the soft start setting.
Check the signals on plug XPS and the
wiring
Check the signals on plug X2D
and the wiring
Check the signals on plug X2D and the

Electrical Data
Vibration Resistance (DIN EN 60068-2-6): 0.35 mm ± 0.05 mm displacement at 10
Hz–55 Hz.
Shock Resistance (DIN EN 60068-2-27): 30 g with 18 ms duration.
Shock Wave Form: Sinus half-wave.
Safety Classification: Max. category 4, PL e, SIL 3.
Mean Time to Dangerous Failure: See B
Common Cause Failure – CCF: > 65.
Diagnostic Coverage (DC): High, 99%.
Monitoring: Dynamic, cyclic, internal.
Noise Level [dB (A)]: The sound pressure level is influenced by the individual
systems to reduce noise emissions. Exhausting of the valve may not be restricted. We
do not recommend using the product without silencers.
Minimum Operation Frequency Recommended: 1 x per month, to ensure proper
function.
Maximum Cycle Rate: 2 Hz.
Mounting Orientation: Any, preferably vertical.
Solenoids: Per VDE 0580. Rated for continuous duty. Electrical connection according
to EN 175301-803 Form C. Enclosure rating according to DIN 400 50 IP 65.
Flow Rates: See page 2.
13. Disposal
Dispose of the valve in accordance with the applicable statutory regulations in your
country.
