JUMO B 70.1050.0 Digital Thermostat Operating Instructions

JUMO B 70.1050.0 Digital Thermostat

Overview of operation

Identifying the instrument

The nameplate with the order code is affixed to the side of the instrument. The supply voltage connected must correspond to the voltage specified on the nameplate. All necessary settings are described in these Operation Instructions. However, if any difficulties should still arise during start-up, you are asked not to carry out any unauthorized manipulations on the unit. This could endanger your rights under the instrument warranty! Please contact the nearest subsidiary or the head office in such a case. Please read these operating instructions before commissioning the instrument. Keep the manual in a place that is accessible to all users at all times. Please assist us to improve these operating instructions, where necessary.

Installation notes

• The choice of cable, the installation, the fusing and the electrical connection must conform to the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with nominal voltages below 1000 V” or the appropriate local regulations.
• The electrical connection must only be carried out by qualified personnel.
• Electromagnetic compatibility (EMC) complies with the standards and regulations cited in the technical data.
• Protect the instrument from electrostatic discharge during installation and operation.
• The instrument is not suitable for installation in areas with an explosion hazard and must be built into a housing that provides protection against fire /electrical hazards.
• Apart from faulty installation, incorrect settings on the instrument (setpoint, parameter level data) may also affect the proper functioning of controlled processes or lead to damage. Provision should therefore always be made for safety devices that are independent of the instrument, e. g. overpressure valves or temperature limiters/monitors. Adjustment must be restricted to specialist personnel (lock parameters for operation). Please observe the corresponding safety regulations in this matter. Unfavorable parameter adjustment may result in unstable control.
• The process value obtained should therefore be monitored for its stability and knowledge about the process should be obtained.
• The load circuit must be fused for the maximum relay current in order to prevent welding of the output relay contacts in the event of a short circuit.
• Do not connect any additional loads to the supply terminals of the instrument.
• If contact with live components is possible while working on the instrument, it must be disconnected on both poles from the supply (via a separate mains supply switch, for instance).

Commissioning the instrument

Displays and controls

• Connect supply voltage – all segments light up twice as a test (segment test).
• When everything has been connected correctly on the instrument, the present process value will be shown.
• If an alarm message appears, see Chapter 7 “Alarm messages”.
• The relay operates according to the controller type that was set, see Chapter 4.2 “Setting the instrument functions (parameter level)”.

Setting the instrument functions (parameter level)

Time-out
If no key is pressed for 60 seconds, the instrument automatically switches back to process value display, see Overview of operation on the first inside page.

• The instrument functions and values are set at the parameter level.
• Press for 3 seconds and will appear alternately.
• Set code 72 for accessing the parameter level by using the keys.
• The longer the key is pressed, the faster the value will change.
• Acknowledge with, parameter name and value appear alternately, e.g.
• Set a value within the specified value range by using the keys.
• Acknowledge settings with.
• Set the next parameter, see Overview of operation on the first inside page

Controller

Allocating user rights (enabling level)

The setting at the enabling level defines user rights which determine whether a parameter is shown at the operating level, can be edited or is not shown at all.

• Press for 3 seconds and appears.
• Set code 82 for accessing the enabling level using
• Acknowledge with Parameter and User rights blink in alternation e. g.
• Use the keys to set the user’s right
