The H41q and H51q System Families
Notes to the Manual
This manual contains the description of the Programmable Electronic Systems (PES) of the
HIMA system families H41q and H51q.
Beside this manual and the data sheets you will find further informations to the system families
H41q and H51q on the ELOP II CD.
The first part contains general notes to the PES and is followed by the description of the indi-
vidual types. All the descriptions have the same structure so that they can each be used inde-
pendently as device documentation.
The descriptions are followed by general information about both system families, e.g. technical
data, test standards, applications, start-up and maintenance.
The second part of the manual contains all data sheets of the systems and the modules. Each
type of PES has a corresponding assembly kit.
After the descriptions of the systems and the assembly kits the data sheets are arranged in
alphanumerical order according to their type numbers.
HIMA Automation Devices are developed, manufactured and tested according to the relevant
safety standards. They must only be used for the applications described in the instructions and
with specified environmental conditions, and only in connection with approved external devic-
es.
In case of unqualified interventions into the automation devices, de-activating or bypassing
safety functions, or if advices of this manual are neglected (causing disturbances or impair-
ments of safety functions), severe personal injuries, property or environmental damage may
occur for which we cannot take liability.

The HIMA PES The H41q and H51q System Families
2
1 The HIMA PES
The HIMA PES described here consists of the H41q and H51q system families. Both system
families are based on the same hardware and software, and they are the third generation of
the field-proven HIMA PES to control preferably process engineering plants. PCs (PADT)* are
used for programming, configuration, data logging, operation and trend recording.
Digital and analog inputs can be processed. Some input modules are designed for intrinsically
safe circuits as well as for electric position sensors (proximity switches) according to DIN EN
60947-5-6. Digital and analog outputs are also available.
The HIMA PES are installed in 19-inches subracks. The H41q system family is a compact sys-
tem consisting of one subrack, holding all components such as central unit, interface exten-
sions, communication modules, power supplies, fusing and power distribution, as well as input/
output modules.
The H51q system has a modular structure. A central rack contains the central unit(s), interface
exten-sions, communication modules, monitoring and power supplies, and it can have up to 16
associated input/output subracks.
*PADT = Programming and Debugging Tool

2 Concept of the HIMA PES
The HIMA PES of the H41q and H51q system families consist of 19 inches subracks for central
devices 5 HU and modules for binary and analog input/output signals which are assembled in
H51q systems within 19 inches subracks, 4 HU.
The HIMA PES use PCs (PADTs) with the tool ELOP II for programming, configuration, mon-
itoring, operation and documentation. The entry of the user program and the compilation into
the machine code is made only on the PC without connected PES. To load, test and to monitor
the PES the PC is connected via a serial interface RS 485 or a bus system to the PES.
2.1 Safety and Availability
HIMA PES are designed both for safety-related applications up to SIL 3 (definition according
to IEC 61508) and for high availability. Depending on the required safety and availability, HIMA
PES can be supplied as one-channel or two-channel (redundant) devices with the same mod-
ules in the central device as well as in the input/output level. Redundant modules increase the
availability, as in case of an error in a safety-related module this is automatically switched off
while the redundant module continues the operation.
The following table gives an overview:
1) Individual I/O modules can also be used as redundant modules or connected to sensors in
a 2-out-of-3 voting to increase the availability.
The inputs have to be therefore configured on 3 different I/O modules.

2.2 Designs and Types of the PES
The controls can be adapted to the requirements of the plant by equipping them with the ap-
propriate central modules. The following structures are possible with the H41q or H51q system
family:
* Central modules, communication modules and I/O modules are installed in the system sub-
rack.

3 The H41q System Family
The H41q system family comprises compact designed PES in single channel and redundant
models, also with TÜV safety certificate.
All input/output modules can be used with both redundant and single channel models of the
central modules.
All modules of the H41q system family meet the requirements for electromagnetic compatibility
and immunity according to article 10 of the EG guideline 89/336/EWG for the electromagnetic
conformity. This is demonstrated with the CE sign within the data sheets of the modules. Also
the systems and modules are wearing a label with this sign.
All models of the H41q system family have all the components required for control tasks in one
19 inches subrack, 5 units high, with an integrated cable tray (see also data sheets of H41q
systems or assembly kits).

3.2 Concepts of the Safety Switch-Off at H41q
In the system descriptions of the safety-related PES H41q-MS, -HS, -HRS the ways for shut-
down if a fault occurs are shown. Depending on the fault location the reactions of the systems
are fixed or they can be defined in the user program.
Parameters are set
– in the resource properties I/O parameter
– by activating of a system variable for emergency shutdown
– via function block H8-STA-3.
An overview of the system variables including the corresponding error code you will find in the
operating system manual.

Explanations to the table:
Parameter “Display only“
Switch-off by means of the integrated safety shutdown inside the output amplifier. If not possi-
ble then shutdown of the watchdog signal in the I/O rack by means of the coupling module (only
in systems H51q). No shutdown of the watchdog signal of the appertaining central unit. This
parameter is permissible only up to SIL 1.
Parameter “Normal operation“
Reaction as with parameter “Display only“, additionally switch-off of the watchdog signal of the
appertaining central unit if necessary. Parameterization required from SIL 2. Normal and re-
commended parameter.
Parameter “Emergency off“
Switch-off of the watchdog signal of the appertaining central unit and thus shutdown of the out-
put amplifiers in case of a fault in the output module.
The watchdog signal is not switched off at faults in the input modules.
Module switch-off
A faulty testable output module with integrated safety shutdown will be switched automatically
to the safe de-energized status.
Group shutdown
If it is requested, a group shutdown may be defined in the user program in a way that all test-
able output modules appertaining to the group with the faulty module are also switched off.
Inside the user program up to 10 testable output modules can be assigned to one group by
means of the function block H8-STA-3.
WD switch-off of the appertaining CPU
In case of a fault the watchdog signal (WD) of the appertaining central module is switched off.
If systems with redundant central modules and a common I/O bus are used then the output
modules are related to both central modules. In case of a fault both the watchdog signals of
the central modules are switched off. That means all the I/O modules are switched off (only at
H41q-H/HS).
If systems with redundant central modules and redundant I/O bus are used then the output
modules are related to one central module and one I/O bus. In case of a fault only the watchdog
signal of the related central module is switched off. That means only the related I/O modules
are switched off (only at H41q-HR/HRS). The redundant central module is still in operation.
3.3 The Input/Output Level
In the subrack, slots 1 to 13 are provided for the input/output modules. Any arrangement of
I/O module types is possible. In PES with redundant I/O bus, the modules on slots 1 to 7 are
assigned to the first I/O bus and 8 to 13 to the second I/O bus.
There is an integrated cable tray under the subrack. It is equipped with a receptacle for the
label which can be flapped open to provide easy access to the cables.
3.3.1 24 VDC Supply and Distribution
For 24 VDC supply and distribution we recommend to use the K 7212, K 7213, K 7214, K 7215
subassemblies or fuse distributor K 7915.
They include all components for the fusing of up to 18 individual supply circuits with circuit
breakers.
The K 7212 is additionally equipped with decoupling diodes and filters with monitoring relays
for mains supply.
Additionally you could use also a power supply of the PS1000 series (see ELOP II CD).

3.3.2 I/O Modules
The I/O modules are used for signal transfer and signal matching between the plant and the
central modules. The input and output circuits are always fed into the I/O modules via cable
plugs on the front side. The status of the digital output signals is shown on the LEDs of the
cable plugs. The power supply is either via the cable plugs or via the I/O bus board. The order
of the different I/O module types does not matter.
All I/O modules can be removed or inserted during operation (see chapter 8.1.1).
3.3.3 ATEX (Ex)i-Modules
The current (Ex)i modules exist in 2 construction models:
– non-varnished, with PCB covering
– varnished, with PCB covering
Any models can be equipped together without empty slots between them.
Non-varnished (Ex)i modules may combined together with non-(Ex)i modules without any re-
strictions. There are no free slots necessary on the left or on the right.
With varnished (Ex)i modules with PCB covering the right slot has to remain free in combina-
tion with non-(Ex)i modules, or has to be equipped with a front plate with partition plate
(M 2214). This is also valid for slot no. 15. The slot left to the (Ex)i module may be equipped
with any other module. Spare slots have to be covered by front plates M 2215 (4 spacing units
SU) or M 2217 (8 spacing units SU).
Usable front plates with partition or front plates:
M 2214 Front plate with partition plate 100 x 160 mm
M 2215 Front plate 4 SU
M 2217 Front plate 8 SU
Cable plugs for intrinsically safe circuits are marked and have coded pins, so that they can only
be plugged into the appropriate modules.
3.3.4 Safety-Related Output Modules for SIL 3
All the safety-related output modules meet the requirements of SIL 3.
The safety-related output modules have three semiconductors connected in series. That
means that more than the required second independent component for safety shutdown is now
integrated in the output module.
In case of a fault of an output module the requirements of SIL 3 are valid without time limit. In
the following this feature is called the integrated safety shutdown.
If a safety-related output module should fail during operation then it will be automatically
switched off by the integrated safety shutdown to get the safe de-energized status.
3.3.5 Special Features of the Output Modules
All output modules have the following special features:
– To increase the availability the outputs of the safety-related output modules can be
switched in parallel without external diodes.
Decoupling diodes are already integrated on the module (see the corresponding data
sheets).
– No output voltage is generated if the supply voltage L- is cut at the output module.
– The connection of inductive loads can be done without using protection diodes at the coil.
However, it is recommended to connect a diode directly at the inductive load avoiding
noise voltages.
– The LED signaling the output status is controlled separately.

The H41q System Family

– The design of the cable plugs enables the two-pole connection of the actuators. Together
with a two-pole supply of the output module an earth fault detection will be simplified by
means of a totalizing current transformer.
The cable plugs are available in two specifications:
• L- in cable plug, one-pole with common L-
• L- in 2-pole type, 2-pole with L- per channel
see also chapter 10.13.6 , “Description of the Order Code for Cable Plugs”, option P2
• No time-limited operation in case of a faulty output module.
3.4 System Voltage 24 VDC
HIMA systems will be connected to 24 VDC. The connection terminals are labelled with L+ and
L-. The power supply units made available by HIMA, e.g. the power supply PS1000, meet the
requirements according to CE for electrical safety and EMC.
All used power supplies must fulfill the requirements SELV (Safety Extra Low Voltage) or PELV
(Protective Extra Low Voltage). See also chapter 6.4.
The power supply units meet the requirements of the NAMUR recommendation NE 21 for the
safety during short-time voltage dips up to 20 ms.
For the supply of 24 V sources, which cannot guarantee a buffering during voltage dips of at
least 20 ms, the following measures must be taken in the H41q system family:
• decoupling of the power supply for the central units and
• noise blanking (parameterizable).
Note Due to the high inrush current of lamps the correct dimensioning of the
power supply units for lamp loads must be regarded.

4 The H51q System Family
The H51q system family comprises modular designed PES in single channel and redundant
models, also with TÜV safety certificate.
All input/output modules can be used with both redundant and single channel models of the
central devices.
All modules of the H51q system family meet the requirements for electromagnetic compatibility
and immunity according to article 10 of the EU guideline 89/336/EWG for the electromagnetic
conformity. This is marked with the CE sign within the data sheets of the modules. Also the
systems and modules are wearing a label with this sign.
The H51q system family consists of one 19 inches central rack, 5 units high, and up to 16 input/
output racks in the 19 inches size, 4 units high (see also data sheets for H51q systems or as-
sembly kits).
