5.0 Operating procedures
Take care when lifting and removing the lid as it may be hot. Steam and hot
vapours can cause scalding.
5.1 Operation
5.1.1 Liquid level
The minimum and maximum liquid levels are defined in section 6.4 for Grant accessory
baths. Liquid level should always be maintained between these levels. These levels
apply both when there are no vessels in the bath and with the maximum contents. If
using liquids that can evaporate then periodic checking and refilling should be completed.
The low level float switch will alarm if the liquid level drops below the minimum required
level and the unit will switch off the heater and stop temperature control.
5.1.2 Operation above 60°C
A lid or polypropylene spheres must be used above 60°C to maintain temperature control
and to ensure that the bath fluid temperature reaches the set point. They will save
energy by preventing excessive evaporation and reduce the frequency that the bath
needs to be refilled. As a precaution, the TX150/TXF200 may display ‘Overheatingpower reduced’ if heating water at or near boiling over extended periods or heating large
volumes of liquid with large thermal losses without the use of a lid or polypropylene
spheres. In this event the heating power is reduced by 50%. See section 11 for
additional guidance.
Care should be taken to ensure rear inlet vents are clear and minimise the intake of
steam or fumes when operating at or near water boiling or with other evaporating liquid.
5.1.3 Operation at low temperatures
Accessory cooling is required for controlled operation at or below ambient temperature.
The minimum working temperature without accessory cooling depends on the size of the
bath. The small baths, P5 and ST5, have a minimum working temperature of
approximately 10°C above ambient without a lid and 15°C above ambient with a lid.
Other bath sizes can be used at a temperature of 5°C above ambient.
5.1.4 Using the pump
The TX150/TXF200 allows liquid to be pumped around a closed external system (not
open to the atmosphere). It may be used for circulation through an external open tank
only if a gravity feed return is present. An assessment of any open system should be
completed to ensure liquid levels are stable during operation and there is no chance of
any reservoir running dry or overflowing. The pump is fitted with a blanking plate as
standard. Fit a pump connector plate as shown below. Note: the blanking/connector
plates have a locating hole (see A below) to assist correct alignment onto the pump
moulding. It is important to verify the hole is aligned with the corresponding locating pin
(see B below) on the pump moulding. Failure to do so will result in a leaking connection.
Retain the blanking plate for refitting when the pump is no longer required.
TX150 & TXF200 30424 V6
Operating Manual Page 10
www.grantinstruments.com
Always use pump connectors and hoses that are suitable for the operating
temperature and liquid used. Check the pipe connections are secure.
Never disconnect any pipes or hoses while they contain very hot or very cold
liquids or while the TX150/TXF200 is pumping.
The relay is rated 24Vac or dc at 2A; to prevent injury or equipment damage, do
not connect to greater voltages or attempt to switch greater currents.
Voltages as low as 22Vac can be hazardous in locations where wetting of the
skin can occur. When making up cable to connect your equipment to the relay
connector, on the TX150/TXF200, make sure that the insulation system used is
adequate to provide protection against the voltages output by your equipment
for switching by the relay.
Always use the correct size cable with correct class of insulation for the voltage
being switched. If in doubt contact the technical support team at Grant.

Pumping heat transfer liquid around an external system can lead to hazards that are
outside the control of Grant Instruments. It is essential that the user conducts a risk
assessment of the entire equipment installation to ensure that correctly rated materials
have been used throughout and that the system can be used safely.
5.1.5 Using the switch over relay output
An internal relay provides switch over contacts that can be used to control external
equipment. The pin connections on the rear panel 3 pin circular connector are:
For the connecting cable use a mating XLR style connector such as the NC3FXX
manufactured by Neutrik AG
The switch over contacts are rated at 24V AC or DC 2A maximum.

5.1.6 Emptying the ST baths
Allow the liquid temperature to fall to a safe level before emptying or moving.
The ST12, ST18, ST26 & ST38 baths should be emptied to a safe level prior to moving.
A drain tap is included on these baths to allow convenient emptying.
CAUTION: if the bath is drained at temperatures above 50°C then the drain mechanism
will be damaged and will need to be replaced. Take reasonable precautions to prevent
accidental spillage.
Empty the bath by pushing the supplied drain insert into the drain tap as shown below.
Note that the bath liquid will begin to empty as soon as the drain insert is fully engaged.
A length of hose can be added to the barbed end of the drain insert if required.
5.1.7 Setting up and switching on
Attach the TX150/TXF200 securely to the required bath or vessel. Add the appropriate
working liquid to the bath to at least the minimum recommended fill level such that the
float level switch is fully raised.
Connect the TX150/TXF200 to a grounded (earthed) electrical power supply with voltage
and frequency within the range specified on the serial number plate.
Switch on the TX150/TXF200 using the power switch on the rear of the unit. The motor
will start immediately and the buzzer will sound while the unit starts up. During start up
the display will show the software version before displaying the home screen. The
TX150/TXF200 is ready to use.
To disconnect the equipment from the mains supply, remove the mains plug from the
mains supply outlet.
5.1.8 Power loss
If power is lost, either due to the unit being switched off or due to a power failure, then
when the power is restored the unit will return to the home screen (see 5.2.7) with the
last valid set temperature and pump speed. Note that, if a program was running (see
5.2.13), the set temperature will be the one set before the program started. If a preset
was in use (see 5.2.11) then the set temperature and pump speed will be correct but the
preset number will not be displayed. The countdown timer (see 5.2.12) will be stopped.

An over-temperature cut-out dial with a temperature scale is located at the top right of the
unit. The over-temperature probe independently monitors the bath temperature and
switches the heater off if it goes above the cut-out threshold.
Coarse setting of the over-temperature thermostat
Rotate the temperature cut-out dial in line with the marked scale to the desired setting.
This should be higher than the set temperature to avoid operating the cut-out before the
set temperature has been reached.
If the alarm is triggered the sounder can be silenced by pressing either the F or S button
once. To continue to use the TX150/TXF200, let the bath liquid cool by at least 5°C,
either naturally or by replacing the liquid, switch the unit off, wait 10 seconds and switch it
on again to clear the alarm. To avoid nuisance tripping the trip point needs to be set at
least 5°C above the desired control temperature.
Alternative setting of the over-temperature thermostat
Rotate the temperature cut-out dial to maximum (or at least a value above the level
required) and configure the set temperature to the cut-out level required. Leave the bath
to reach the set temperature and stabilise for at least 5 minutes. Turn the cut-out dial
slowly anticlockwise until an over-temperature fault is displayed on screen and the alarm
sounds continuously. This gives an over-temperature trip point at the set temperature.
The audible alarm can be cancelled by pressing either the F or S button once.
To continue to use the TX150/TXF200, let the bath liquid cool by at least 5°C, either
