6 Installation and commissioning

6.1 Mechanical installation

The HDA 5500 is a control panel unit with a standard mounting housing 96 x 48 mm and requires a control panel cut-out: 92 x 45 mm

• Control 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 the country concerned (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

conditions 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 or regenerative diodes must be used on the load to prevent high switch-off surges.

9.1 Standard display

Point 7.2 lists the options which you can select as the primary display. The value set at any one time is displayed permanently.

Hints:

• Initialisation of the HYDACLab ® can take up to 2 minutes; only once the initialisation has

been completed are the measured values meaningful.

• 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 less than 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 one of the measured values (temperature, rel. humidity, rel. change in viscosity or dielectric constant when device HLB 1000 is selected, or CH1, CH2, CH3, CH4 when device CS 1000 is selected) is set as the primary display, then by pressing the

values can be displayed separately. These values are each displayed for approximately 3 s:

• Lowest value

• Peak value

• Status signal

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

10 Output response

The HDA 5500 has an analogue output which is proportional to an input signal. The analogue output can be allocated to each of the signals (rel. change in viscosity, rel. change in dielectric constant, rel. humidity, temperature when device HLB 1000 is selected, or CH1, CH2, CH3 or CH4 when device CS 1000 is selected).

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 relevant measured variable (see Point 7.2). The signal can be adjusted as required.

10.1.1 Analogue output set to 4..20 mA

Connection example for analogue output set to 4..20 mA.

Iout = 4..20 mA

If the input signal is less than 3.7 mA, a cable break is detected. The initial value of the measuring range will then flash constantly and the analogue output (only in 4 ..20 mA mode) continually supplies a current of 3.5 mA.

10.1.2 Analogue output set to 0..10 V

Connection example for analogue output set to 0..10 V.

10.2 Switching outputs

Each switching output consists of a relay, the switching contacts of which can be connected as N/C or N/O. For each switching output, the following parameters can be set during normal operation (see Point 7.2 Overview of the Basic Settings Menu):

• Assignment to sensor signal

• Switching function (switch point and hysteresis or switching window mode)

• Switching direction (relay activated or relay deactivated)

• Switch-on delay

• Switch-off delay

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 mode (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 mode 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 % FS and lower switchback point = lower switch point minus 1 % FS). 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 2.25..99 % of the display range

• Lower switch point 1.5..98.24 % 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.

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 80%, the hysteresis to 100%.

Action: Correct the hysteresis setting.

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

display range (LR) and upper limit of display range (UR) is too low.

Examples:

LR = 0.025 => Minimum value for upper display range = 0.125 LR = 0.25 => Minimum value for upper display range = 1.25 LR = 2.5 => Minimum value for upper display range = 12.5 LR = 25 => Minimum value for upper display range = 125.0 Action: Correct measuring range settings as follows: LR = 0.0XX => Minimum value for upper display range = 0.1XX LR = 0.XXX => Minimum value for upper display range = 1.XXX LR = X.XXX => Minimum value for upper display range = 1X.XX LR = XX.XX => Minimum value for upper display range = 1XX.X

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, switch points, switch-back

points and basic settings) and correct them if necessary. If the errors occur

frequently, please contact, please contact our Service Department.

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 short-

circuited against AGND. Check that the maximum current has not exceeded 100

mA.
