provides a diagnostic coverage of up to 99%. Monitoring of these switches must be
done by an external monitoring system.
The unit cannot be used by itself. It is designed for installation in a machine. ROSS
and its suppliers will assume no liability in the event that the system or parts thereof
are not used in accordance with their designated use or if modications are made in
a non-authorized manner.
Any drawings, hydraulic or electric circuit diagrams, parts lists and acceptance
certicates (inspection reports) supplied do not form a part of these operating
instructions. They are supplied for the purpose of illustrating the unit or procuring parts.
2.1.1. Safety Function According to ISO 13849
HBB Series Block and Bleed systems are designed in accordance with the requirements
listed in ISO 13849-1 and -2. Their “fail-to-safe” safety function is ensured even in case
of a fault within the valve (e.g., caused by power loss, wear, contamination, or similar
situations).
The safety function of the HBB Series Block and Bleed system is to only supply ow
and pressure into the machine/system when the two valve elements are actuated
simultaneously, but to shut-off the supply and to bleed the downstream pressure
back to tank when both valves are shut off or if only one of the two valves is de-
actuated.
A fault in the system where only one valve actuates when switching on or only one
de-actuates when switching off prevents ow of hydraulic uid from being supplied
downstream. Monitoring of the two inductive position switches by the user’s external
safety control & monitoring system makes it possible to detect these fault situations
and to shut off and prevent further electrical energization of the solenoids until the
fault is cleared.
Port identication on the manifold according to ISO 16874
The HBB Series Block and Bleed system is designed and manufactured in accordance
with the identication requirements laid out in the ISO 16874:2004 standard.
2.1.2. Common Cause Failure – CCF
The product has been engineered and manufactured according to the fundamental
and proven safety principles of ISO 13849-1 and -2.
Common Cause Failures (CCF) are failures of different components, resulting from
a single event. CCF are not to be confused with cascading faults or common mode
faults. Common cause failures can cause loss of the safety function, especially in dual
channel circuits where both channels could fail simultaneously due to a single event.
• Maintain hydraulic uid quality, i.e., proper ltration.
• Operate within prescribed temperature limits.
• Install the valve such that the normal stroke travel of the valve elements is
perpendicular to the main direction of machine vibration and/or mechanical shock.
• Avoid external magnetic elds.
• Do not use a test pulse longer than suggested in the Integration Guide.
• Do not plug the T port or Y port (where provided). These ports should be piped to
the reservoir.
2.1.3. Diagnostic Coverage
A diagnostic coverage of 99% is achievable through appropriate integration of the
HBB Series Block and Bleed system into the safety control system. The monitoring
system must constantly compare the state of each valve’s inductive position switch
(Switch 2A & Switch 3A) with the state of the safety control system outputs to the valve
solenoids (Sol 2A & Sol 3A). Detection of a fault by the safety control & monitoring
system must trigger a shut-off of the safety controller’s outputs to the valve solenoids
(Sol 2A & Sol 3A).
2.1.4. Fault Modes
Note that normal operation requires that Sol 2A & Sol 3A be energized simultaneously
for switching the HBB Series Block and Bleed system on, and de-energizing both Sol
2A and Sol 3A simultaneously for switching the HBB Series Block and Bleed system off.
NOTE: The switches are supplied with both NC and NO contacts. The statements
below only refer to whether or not the switches are actuated.
Faults that could occur during normal operation are:
Sol 2A & Sol 3A energized simultaneously
Switch 2A ON, Switch 3A OFF
Switch 2A OFF, Switch 3A ON
Switch 2A OFF, Switch 3A OFF
Sol 2A & Sol 3A de-energized simultaneously
Switch 2A ON, Switch 3A OFF
Switch 2A OFF, Switch 3A ON
Switch 2A ON, Switch 3A ON

2. Notes on Safety
The product has been manufactured according to the accepted rules of current
technology. There is risk of injury or damage if the following safety instructions and
warnings given in this instruction manual are not observed.
2.1. Intended Use
The HBB Series Block and Bleed Control systems are safety components designed and
manufactured in accordance with Machinery Directive 2006/42/EC.
The HBB system is comprised of two single valves (direct solenoid-operated spool
valves on D03 and D05 sizes & solenoid pilot-operated valves on D07 size) which make
it a redundant design for meeting the needs and requirements of safe hydraulic block
and bleed applications. Typically, these systems are designed to meet Category 4, PL e,
SIL 3 applications if properly implemented into the safety control & monitoring system.
The HBB Series Block and Bleed system is designed to allow the ow of hydraulic uid
into a hydraulic system and to block that ow and simultaneously bleed downstream
energy when needed.
NOTE: Block and Bleed functions are intended to permit ow when switched on
and to block supply and to bleed off downstream energy when switched off or in a
faulted state. It is important to note that the ability to bleed may be affected by other
components downstream of the HBB valve. PO checks, counterbalance, and closed-
center valves are designed to block ow under certain conditions. Depending on the
application, these devices may be detrimental or they may be benecial to complete
the needed safety function. Careful consideration of the required safety function and
how to achieve that goal is absolutely necessary.
NOTE: HBB valves are intended to be used only for tasks that are routine, repetitive,
and integral to production. Maintenance tasks require following full lock-out/tag-out
procedures to relieve hazardous energy and prevent unexpected startup.
During normal operation the HBB system is held actuated, allowing the ow of
hydraulic uid through the HBB unit from inlet to outlet. In a situation when immediate
pressure and ow shut-off is needed, the HBB Series Block and Bleed system can be
turned off to provide an immediate ow and pressure blocking action, and provide a
path to tank for downstream hydraulic uid.
The HBB Series Block and Bleed systems are designed to be externally monitored by
a safety control & monitoring system for safe, redundant operation of the valves. Each
single valve is equipped with a PNP inductive position switch. Monitoring both of these
switches on each actuation and de-actuation of the HBB Block and Bleed system

2.3. Safety Instructions
The HBB Block and Bleed System features a state-of-the-art design. Reliable and
safe operation cannot be ensured unless all the instructions, settings and output limits
applicable to the unit supplied are adhered to.
The systems involved are pressure-generating systems whose components feature
pressurized liquid; consequently, the systems may pose a hazard if not dealt with
properly.
2.3.1. Additional Safety Considerations
• When implementing surge suppression measures, be sure to check whether or
not this extends the valve system 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 system.
• Operate only with the proper supply voltage. Improper voltage supply can damage
solenoids and switches.
• Excessive hydraulic uid temperature can damage valve seals as well as cause
premature degradation of hydraulic uid. Both of these situations can cause improper
operation of the hydraulic system.

hoses, in-line mounting kits, and electrical connectors must be subjected to the
same examination.
7.1.2. Filtration: Fluid cleanliness is a necessity in any hydraulic system. Fluid
lters need to be installed and maintained in the system to provide the required level
of cleanliness. Filters can be placed in the inlets. See Maximum Fluid Contamination
under Specications, page 7.
7.1.3. Accessory Ratings: All accessories used in combination with the selected
or intended HBB valve system must be used in accordance with the HBB specications.
7.1.4. Spool Valve Replacement
WARNING
Risk of Injury!
Misuse may result in injury or damage.
fThe product must be used exclusively as intended.
fThe individual spool valves must only be replaced with the appropriate
type and model number and installed only in the proper manifold position.
The individual spool valves designated as 2A and 3A have different spool
configurations. The 2A valve spool has a closed cross-over condition while
the valve is shifting and the 3A valve spool has an open cross-over condition
while shifting. After any disassembly, care should be taken to ensure the
correct valves are re-installed or replaced at the correct position on the
manifold. Refer to the engravings on the top of the manifold for proper valve
positioning. On the size D07, this note refers only to the main spool valves -
the pilot valves are identical.
7.2. Electrical Connections
Use two DIN EN 175301-803, Form A type electrical connectors to connect to the valve
solenoids.
Use a female M12 cord set (4-pin or 5-pin, A-coded) to connect to each inductive
position switch according to the electrical wiring schematic of the switches on page 7.
8. Commissioning and Operation
Before commissioning, the installation must be carefully inspected by a qualied,
trained professional.
Make sure that the technical specications match the operating criteria of the machine

NOTE: PNP (M12, 4-pin, A-coded, male); works with both 4-pin & 5-pin female cord sets.
Please note that the function of the switch varies depending on valve size. As a
result, in the normal valve off condition, the D03 & D05 valves utilize pin 2 of the
switches as NC outputs and pin 4 as NO outputs. On the D07 size valves pin 4 is
used as the NC output and pin 2 is used as the NO output. This is due to the fact
that in the valve off condition on the size D07, the switches are in the actuated
condition when the valve is off.
