SECTION 1 - INTRODUCTION The SMX 100 microprocessor-based system uses modern technology to ensure that the cold-room is controlled and monitored with the greatest of ease. The large graphics LCD display communicates the information to the user with clarity, making programming and setting up friendly and uncomplicated, without compromising its sophistication and digital accuracy.
SECTION 2 – INSTALLATION NOTE: This installation procedure is for guidance only, and its suitability should be verified by the installer. It is assumed that the refrigeration plant is physically installed and tested, and is ready for operation and connection to the electric supply. SAFETY PRECAUTIONS The following safety precautions are strongly recommended: Before attempting to install and operate the unit, read this instruction manual...
2.1.2 Fasten the screw corresponding to the top centre lug on the back of the SMX 100 unit, into the wall or panel on which the control box is to be mounted. Leave a gap of approximately 3mm between the screw head and the wall.
2.2.3 Install the product sensor either to measure the air temperature or product temperature (or simulated product), as required, depending on the application. The SMX 100 uses the temperature measured by this sensor for logging purposes only. ALARM RELAY NOTE: The alarm relay is a 3 contact changeover arrangement which is isolated (volt-free).
1 hour, and maintaining the system clock. If a longer period of mains failure is anticipated, a battery kit of up to 72 hours capacity can be supplied by Thermomax. If the power cut takes longer and the battery has discharged, the clock must be reset when the power supply is re-established.
SECTION 3 - SMX 100 OPERATION In order to fully understand the operation of the SMX 100, this section should be read carefully. 3.1 - DESCRIPTION GRAPHICS LCD DISPLAY Displays all the information. The contrast is adjustable to suit the user.

Please refer to the back of this manual. Defrost Two options are available: ELECTRONIC DEFROST: This is the default setting for the SMX 100 defrost option. Press and hold the key for 5 seconds to select the “ELECTR” option. Relay status: COMPRESSOR...
DEFROST SCREENS: Real-time Defrost Settings DEFROST Function Selector There are 12 programmable defrost cycles, divided into two groups of 6 cycles. Defrost Screen 1 shows cycles 1 - 6, and defrost Screen 2 shows cycles 7 - 12. Each group of 6 defrost cycles has its own duration, termination temperature and dwell period.
Page 16
Defrost Dwell Timer (0 - 99 min.) The defrost dwell time is set here. After a defrost cycle, whether the cycle has terminated by time or temperature, a dwell period can be programmed (for drain off), or set to ‘0’ (no dwell).
ALARM / DIAGNOSTIC SCREENS 3.5.1 ALARM SCREEN: High & Low Level Alarm Preset ALARM Function Selector Alarm Mute To mute the audible alarm, press the key when MUTE / RESET is selected. NOTE: Also, pressing any key the alarm will be temporarily muted for 3 minutes.

Low Alarm All the functions described in 4 - 6 above also apply to the low alarm. Status Window This window shows the current state of the system. If there are any warnings or messages, they will be displayed here and, by referring to the diagnostics screen, further investigations may be carried out (see 3.5.2).
This is the unique electronic signature of the SMX 100. The INPUT TYPE window shows which type of sensor is being used. (PT100 in this case. PT100 is the only type used by the SMX 100 at present). The ROOM, EVAPORATOR and PRODUCT sensor calibration data is shown there, respectively.
3.5.3 DATABANK DIAGNOSTICS SCREEN This is the unique electronic signature of the SMX 100. The DATABANK window shows the capacity of the internal databank. The DAYS FREE window shows the total number of days which have not yet been ‘used’.
Defrost Log: This is a graphical display indicating the occurrence of defrost cycles throughout the day. Alarm Log: This graphically displays the occurrence of any alarms throughout the day. It combines indications of a high alarm trigger, low alarm trigger, or mains-fail. Unique electronic serial number of SMX 100.
3.6.2 PLOT HISTORY: Data log of previous days PLOT Function Select Key Pressing this key a second time displays the directory of the contents of the internal databank, enabling the user to access previously recorded data. The highlighted months on this screen are the months for which the databank contains data.
CALIBRATION TRIMMING Calibration trimming allows qualified personnel to adjust the SMX 100’s calibration by ± 2°C in 1°C steps. Note: A known reference temperature should be used. Press the key three times to select SET SCREEN 2 (Section 3.3.1). Use the key to move to the “CALIB (CODE)”...
DATA TRANSFER The SMX 100 is supplied with an internal reusable databank. The databank capacity is 1064 days (approx. 3 years). When the databank becomes 100% full, the section containing the oldest data will be erased, and new data logged in its place. Each section represents one eighth of the databank (133 days).
