HDA 5500 User Manual

1 Introduction

The individual components and the final assembly of the Digital Display Unit HDA 5500 are
subject to strict quality controls. Each HDA 5500 is individually calibrated and subjected to a
final test. In this way we can guarantee that the unit is fault-free on despatch and conforms to
the given specifications. However, if there is a cause for complaint, please return the unit to
us outlining the fault.
The HDA 5500 digital display unit is maintenance-free and operates perfectly when used
according to the specifications. If faults do nonetheless arise, please contact HYDAC Serv­ice. Incorrect installation or interference by anybody other than HYDAC personnel will
invalidate all warranty claims.

1.1 European standards compatibility

The HDA 5500 digital display unit carries the
approval requirements currently applicable in Germany and to the European standards for
operating these units. The applicable directives on electromagnetic compatibility and the
safety regulations according to the low voltage directive are therefore guaranteed.
This product complies with the regulations of the following European Directive:

EN 61000–6–1 / 2 / 3 / 4

We reserve the right to make technical modifications.

- mark and therefore corresponds to the

2 Safety instructions

6 Installation and commissioning

6.1 Mechanical installation

The HDA 5500 is a control panel unit with a standard mounting housing with the following
measures for mounting:

• Control panel cut-out of 92 x 45 mm

• Panel thickness: at least 1.25 mm

• Mounting depth: at least 150 mm

Panel clips

Panel thickness

Clamping guides

6.2 Electrical connection

The electrical connection must be carried out by a qualified electrician in accordance with
relevant regulations (in Germany: VDE 0100).

Important:

In order to fulfil the relevant EMC standards, subject to the ambient conditions, the screening
effect of the control box must comply with the EMC standard.

Additional installation notes which, from experience, reduce the effect of electromagnetic
interference:

• Make line connections as short as possible.

• Use screened lines (e. g. LIYCY 4 x 0.5 mm²).

• The cable screening must be fitted by qualified personnel subject to the ambient condi-

tions and with the aim of suppressing interference.

• Direct proximity to interference must be avoided as far as possible.

If inductive loads are to be switched using the relays, varistors must be used on the load to
prevent high switch-off surges.

9 Digital display

9.1 Standard display

According to the particular type, the following list of values can be set as the primary display.
The pre-set value concerned will be continuously displayed.

• SEn.1 (measured value from sensor 1)

The displayed value corresponds to the measured value and is proportional to the input
signal of the corresponding sensor. The values are linear between the lower limit and the
upper limit.

• Min.1 (lowest value from sensor 1)

The displayed value corresponds to the lowest value which has been measured since the
supply voltage was switched on or since the last reset.

• ToP.1 (peak value from sensor 1)

The displayed value corresponds to the highest value which has been measured since
the supply voltage was switched on or since the last reset.

Notes:

• If the measured value exceeds the upper display range of the HDA 5500, then the

measured value can no longer be displayed. The upper display range flashes.

• If the measured value is below 1 % of the lower display range, then the measured value

can no longer be displayed. The lower display range flashes.

9.2 Special display

If a measured value is set as the primary display, then by pressing the
following values can be displayed separately. These values are each displayed for approxi­mately 3 s:

• Lowest value

• Peak value

The relevant lowest and peak values are reset by pressing the
ously during normal operation. If the reset has been successful, rES (reset) is displayed to
confirm this.

The HDA 5500 has a through analogue output which is proportional to the input signal. In
addition, depending on the model and type, without switching outputs or two or four switching
outputs are available.

10.1 Analogue output

On the analogue output a 4..20 mA or 0..10 V signal is available. This signal is proportional
to the input signal of the sensor. It’s type can be adjusted during normal operation.

11 Adjusting switching points and hystereses

Procedure for HDA 5500 without switching outputs:

• During normal operation, press mode key.

Since no switching outputs are available, noSP (no switch point) will be displayed.

• After approximately 2 s the display returns to normal operation.

Note:

If the mode key is pressed for longer than approximately 5 s, then the Basic Settings Menu
will be activated.

12 Programming enable

The unit has two types of programming enable, the operating programming enable and the
main programming enable. Both types must be enabled to change the settings.
The operating programming enable provides protection from unintentional changes to the
settings during normal operation. The operating programming enable can be altered during
operation.
The main programming enable provides general protection from changes to the settings.
The main programming enable can only be altered when the HDA 5500 is switched on.

12.1 Altering the operating programming enable

Procedure:

• During normal operation, press the

and keys simultaneously and hold down for at

least 3 s.

• OPrG (Operating Programming) is displayed.

• After approximately 2 s the display changes and the actual setting is displayed:

Free (programming enabled) or Loc (programming disabled).

• Within approx. 3 s the setting can be changed to Loc or Free by pressing

or .

• If or is not pressed for approximately 3 s or longer, then the displayed setting is

accepted. If a setting has been altered, then ProG (programming) is displayed for ap­proximately 2 s. This means the changed setting is stored in the HDA 5500. Afterwards
the display returns to normal operation.

12.2 Altering the main programming enable

The main programming enable can only be altered when switching on the HDA 5500. If the
HDA 5500 is already in operation, then the supply voltage must first be switched off or the
HDA 5500 must be disconnected from the supply voltage.
Procedure:

• When switched off, press both arrow keys simultaneously and hold down.

• Switch on or connect the supply voltage and at the same time continue to hold down the

arrow keys for at least 3 s.

• MPrG (Main Programming) is displayed.

• After approximately 2 s the display changes and the actual setting is displayed:

17 Error messages

If an error is detected, then a corresponding error message appears which must be acknowl­edged by pressing any key. Possible error messages are as follows:
Er.01 The switching points and hystereses have been set in such a way that the resulting

switch-back point is no longer within the permissible setting range.
Example:
Switching point is set to 180 bar, the hysteresis to 200 bar.

Action: Correct the hysteresis setting.

Er.02 The minimum difference in the given measuring ranges between lower display

range and upper display range is too low.
Examples:
Lower display range = 0.025 and upper display range = 0.075
Lower display range = 0.25 and upper display range = 0.75
Lower display range = 2.5 and upper display range = 7.5
Lower display range = 25 and upper display range = 75
Action: Correct measuring range settings as follows:
Lower display range = 0.0XX => minimum value for upper display range = 0.1XX
Lower display range = 0.XXX => minimum value for upper display range = 1.XXX
Lower display range = X.XXX => minimum value for upper display range = 1X.XX
Lower display range = XX.XX => minimum value for upper display range = 1XX.X

Er.03 The difference of the measuring values between sensor 1 and sensor 2 is outside

the measuring range.
Action: Check all the settings (programming enables, switching points, switch­back points and basic settings) and correct them if necessary. If the errors occur
frequently, please contact HYDAC Service.

E.10 A data error has been detected in the saved settings. Possible causes are strong

electromagnetic interference or a component fault.
Action: Check all the settings (programming enables, switching points, switch­back points and basic settings) and correct them if necessary. If the errors occur
frequently, please contact HYDAC Service.

The display shows four horizontal segments. This means that the sensor supply
voltage (+12 V, plug X2.6) is overloaded.
Action: Ensure that the above mentioned supply voltage of +12 V has not short­circuited against AGND. Check that the maximum current has not exceeded
100 mA.
