1 Safety information

1.1 General safety information

A laboratory thermostat heats and circulates liquids according to specified parameters. This involves hazards due to high temperatures, fire and general hazards due to the application of electrical energy.

The user is largely protected by the application of relevant standards. Further hazard sources may arise due to the type of tempering medium, e.g. by exceeding or undercutting certain temperature thresholds or by the breakage of the container and reaction with the heat carrier liquid. It is not possible to consider all eventualities. They remain largely subject to the judgment and responsibility of the operator. The equipment may only be used as prescribed and as described in these operating instructions. This includes operation by instructed specialist personnel. The equipment fulfills the following classes of the EMC standard EN 61326-1:1997 VDE 0843-20:

Class A: Operation only on networks without connected domestic areas. Class B: Equipment for operation on networks with connected domestic areas. Class B*: Equipment fulfills Class B when a house connection > 100 A is involved. With unfavorable network conditions disturbing voltage variations may otherwise occur.

llation Categories (Over voltage Categories) II.

4.2 Types of unit

The type designation of the Proline Low-Temperature Thermostats comprises the prefix R (to designate the refrigeration machine), a P for Proline, the bath volume in liters and the lowest bath temperature (guide figure without arithmetic sign). Units in Command version are marked with a “C” at the end of the model description.

Examples: RP 855 is a low-temperature thermostat with 8-liter bath and -55 °C min. temperature. RP 1845 is a low-temperature thermostat with 18-liter bath and -45 °C min. temperature.

4.3 VarioFlex pump

All units are fitted with a VarioFlex pump with an 8-stage variable drive. The pump power can therefore be optimally matched to the relevant task: High pump pressure when, for example, long hoses pass to external loads or circulation is to be provided for a large bath. Low pressure when the heat input into the bath must be low.

As a delivery/ suction pump, the VarioFlex pump enables the very effective supply of pressuresensitive glass reactors, which have a minimum permissible pressure rating. Furthermore, open vessels can be operated when a constant level controller (accessory L CZ 0 660) is used.

At the right-hand side and at the back of the unit outflow and inflow nozzles are fitted for external loads. This means that up to two external loads can be directly connected without a distributor. Connections, which are not required, must be closed off with the supplied caps and union nuts. A bypass valve can subdivide the total volume flow variably between the bath (internally) and the connected load (externally). Consequently, no "pump short circuit" is needed. If no load is connected to the pump connector, the bypass valve must be set to the “internal” position for the best bath circulation.

In the heating range, the VarioFlex pump operates up to viscosity values of 150 mm²/s. In the closedloop control mode 50 mm²/s should not be exceeded. The temperature control is the best with 30 mm²/s and lower viscosity.

With small bath coolers (e.g. RP 845) power level 1 to 3 is practicable.

YACE0072 / 21.08.07 Unit description 15

Proline Low-temperature Thermostats

For operation as a circulating thermostat with an external load, a higher power level is practicable to maintain the temperature difference low, among other things also with higher temperatures in conjunction with oils as heat carrier liquid.

The pump connections on the unit are fitted with M16 x 1 thread. The pump outflows of the VarioFlex pump can be closed off without any impairment to the pump.

Here, the "internal" setting of the bypass controller is recommended.

Pump characteristics

(Ì Section 11).

4.4 Materials

All parts being exposed to the heat carrier liquid are made of high quality material appropriate to the operating temperature. Non-rusting stainless steel and high quality temperature-resistant, primarily solvent-resistant plastics are used.

4.5 Temperature display, control and safety circuit

In the Master Version, the units are equipped with a 5-character green LED display, which is used for the display of the measurements and settings, as well as the operating status. The entry of setpoints and other settings occurs under menu guidance via four keys.

The extra features of the Command Version include a removable console with a backlit graphical display. The entry of the setpoint and other settings occurs under menu guidance via situationdependent cursor keys and soft keys.

A Pt100 temperature probe acquires the outflow temperature in the bath. A high-resolution A/D converter processes the measurement. Further measurement conditioning occurs using a special control algorithm for controlling the heater actuator, which has a low reactive effect on the mains, and the SmartCool refrigeration equipment together with further transducers.

An external Pt100 can be connected via a socket (10S) for the acquisition of an external temperature. This value can be displayed and, if required, used as the controlled variable with external control (Master) switched on. In this way, the system controls the external measurement and not the outflow temperature Ì 7.7.4.

The saf parameters. A dual-channel system is used in which two microcontrollers monitor one another. Along with the bath temperature measurement and control probes, there are also two safety temperature probes (Pt100) for the safety circuit for the overtemperature cut-off and for monitoring the bath temperature probe.

The overtemperature cut-off point is displayed on pressing the key Changing the overtemperature cut-off point: Ì 7.2 (Switching on) on page 25. The bath level is acquired

The reaction of the thermostat in case of overfill can be set to simply display a warning, to display a warning and switch off the heater or to switch off the unit completely with pump, heater and SmartCool System refrigerating machine.

When the level is too low, with overtemperature, or with other alarms the SelfCheck Assistant switches the heater off on all poles. The pump and the refrigerating machine are also switched off. This switch-off under fault conditions is retained, i.e. after the fault is rectified, the fault must be reset

4.9 Cooling unit

The refrigerating machine mainly consists of one or two fully hermetically sealed compressors. The heat from the condensation process and the motor is dissipated via a lamellar condenser. Here, fresh air is drawn in at the front of the unit, heated towards the back and output at the side. To ensure proper air circulation the ventilation slots must not be restricted. See Section 6.1.

The co use of the compressor and only then cools when refrigerating capacity is demanded by the controller. To achieve this, a number of sensors in the cooling circuit monitor the operating conditions.

The compressors are equipped with overtemperature cutouts, which respond to the compressor temperature and the compressor current consumption. In addition, the refrigeration system is backed up by a pressure control device against over pressure. The cooling unit is normally switched in automatically, but can be switched manually via the operating menu. (Ì Section 7.6 with Command und 7.6.3 with Master).

4.10 Avoidance of dewing

In order to avoid dewing on the edge of the bath when using the low temperature thermostats RP 855, RP 870, RP 890 and RP 1290, these instruments are equipped with a device for heating the edge of the bath, using the waste heat of the cooling unit. As a standard feature, the minimum temperature thermostats RP 890 and RP 1290 are equipped with an additional electric heating of the bath bridge. This can be ordered as an option for RP 855 and RP 870. With the bath covers of the minimum temperature thermostats, RP 890 and RP 1290, it is possible, by means of a nipple, to let nitrogen or dry air into the bath with a low volume flow.

4.11 Heater rating and power consumption from the mains

The Proline Low-Temperature Thermostats have an extraordinarily high heater rating of 3.5 kW maximum. If your mains fuse is rated below 16A, the current consumption can be reduced in steps from 16 A to 10 A Ì 7.7.5. The maximum heater rating of 3.5 kW i accordingly.

7.7.3 Setting pump power or standby

With the Proline VarioFlex pump, eight pump levels are available, with which the bath circulation, flow rate and pressure, the noise generated and the mechanical heat input can be optimized. This is particularly advantageous with coolers. With smaller coolers (e.g. RP845) without an external load, Power Level 3 to 4 is practicable and sufficient.

7.10 Programmer (PGM only Command)

Almost any temperature/time profile can be created with the programmer. A desired bath temperature can be approached as quickly as possible or via a defined ramp. Furthe rmore, the pump level and the behavior of the switching outputs can be defined. Five temperature/time programs are provided for free programming. Each program consists of a number of temperature/time segments. Also include d are details of how often the program is to be executed (loops). The sum of all segments of all programs may be up to a maximum of 150. Typical segments are:

Ramp: If a time is specified, then the segment is a ramp, which is described by the target temperature, i.e. the temperature at the end of the segment, and the duration from the start to the end of the segment.

Step: Without any specified time the final temperature is approached as quickly as possible. Temperature hold phase: No temperature change (i.e. the temperatures at the start and end of a

segment are the same).

The programmer can be controlled or changed via the RS 232 interface, the timer or

0 20 40 60 80 100 120 t/min

− It facilitates exact conformance to the dwell time at a specified temperature. Segment 1 is not processed until the bath temperature is within the tolerance range n, so that the ramp (Segment 2) starts delayed at o.

− A tolerance range which is too tight can however also cause undesired delays. In particular with external control the range should not be chosen too tightly. In

Segment 5 a larger tolerance has been entered, so that the desired time of ten minutes is maintained even with settling action p.

− Only flat (slow) ramps should be programmed where necessary with a tolerance range. Steep ramps which lie close to the maximum possible heating or cooling rates of the thermostat may be severely delayed by a tolerance range that is too tight (here in Segment 2) q.

Example for the influence of the tolerance field input in case of external bath temperature control:

The setpoint temperature of the programmer is shown in grey.

The actual temperature in the external bath container is represented as a continuous line.
