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: 92 x 45 mm

• Control panel thickness: at least 1.25 mm

• Mounting depth: at least150 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.

9.1 Standard display

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

• SEn.1 (measured value of sensor 1) or SEn.2 (measured value of Pt 100 sensor)

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 of sensor 1) or Min.2 (lowest value of Pt 100 sensor)

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 of sensor 1) or ToP.2 (peak value of Pt 100 sensor 2)

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

• S.P.1 (switch point 1) or S.P.2 (switch point 2) (for HDA 5500-3-1-XC-000) or

4) (for HDA 5500-3-2-XC-000)
The displayed value corresponds to the particular pre-set switch point.

Important:

• 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

• Switch point(s)

• Sensor 1 or 2 (Pt 100 sensor)

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.

10 Output response

The HDA 5500 has a through analogue output, the signal of which is proportional to an input

10.2.1 Switching mode

During normal operation, switch point and hysteresis or switching window can be set as the
switching mode of a switching output.

10.2.1.a) Switch point and hysteresis (SP)

In the switch point and hysteresis mode, a switching function is activated if (while rising in
value) the measured value of a sensor reaches the value of the switch point. A switching
function is deactivated if (when falling in value) the measured value of a sensor falls below
the value of the switch point by the value of the hysteresis. This defines the switch-back point
as the difference between switch point and hysteresis.

The switch point and hysteresis can be set individually for each switching output. The fol­lowing setting ranges apply:

• Switch point 1.5..100 % of the display range

• Hysteresis 0.5..99 % of the display range

10.2.1.b) Switching Window (Win)

In switching window a defined range is monitored. A switching function is activated if the
measured value of a sensor is outside the window and reaches one of the switch points. A
switching function is deactivated if the measured value of a sensor is within a switching
window and reaches one of the switch-back points. The switch-back points depend on the
switch points (upper switch-back point = upper switch point plus 1 % and lower switch-back
point = lower switch point minus 1 %). This difference between switch point and switch-back
point prevents unwanted switching from occurring.

The upper switch point and the lower switch point of a switching window can be individually
set for each switching output. The following setting ranges apply:

• Upper switch point 1.0..99.5 % of the display range

• Lower switch point 0.5..99 % of the display range

Important:

The switching window therefore only functions correctly (activation and deactivation of a
switching function), if all the switch points and switch-back points are larger than the lower
limit and smaller than the upper limit of the display range of a particular sensor.

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:

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

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

the

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.
