CAUTION : Installation and maintenance of this equipment should only be carried out by qualified personnel. Since the HMT LED is connected to a mains supply or 115V, it must be installed in compliance with standard IEC 364. The mains supply for the clock must include a neutral phase circuit breaker (16A maxi), rapidly accessible upstream from the supply.
II.2 Wall fixing Fix the clock with the 4 screws Ø6 (not supplied) (HMT/HMS LED 15, 20 and 25) or the 6 screws Ø8 (not supplied) (HMT/HMS Led 45) and the appropriate plugs. Make use of the 4 oblong holes behind.

III - Electrical installation Advice : to prevent the cable from moving, it is recommended to use cable ties near each cable entry inside the clock. On some clock models, it is necessary to remove one display module in order to freely access the terminal blocks.
III.1 Power supply The switching power supply works normally with 230V 50/60Hz but it can works also with 115V. Nota : the 230V/115V input voltage switch is located under the switching power supply. To access the switch, dismantle the digit in front of the switching power supply, unscrew the HM8 screw and remove the fixing plate.
III.4 Installation on an AFNOR network Connect the cable as shown in the diagram below (non-polarised inputs). The clock sets itself to the right time after receiving several coherent time messages. Between successive synchronisations, the time base changes normally in accordance with the internal base. If the clock is in COD mode (see page 29), the time displayed is the time received.
III.5 Installation on a minute or 1/2 minute network A “Minute” or “½ minute” distribution network only transmits impulses. It is therefore necessary to set the receiver clocks to the time of this network. It is not necessary to stop the distribution to add the clock. Simply set it to the right time and it will increment by one minute on reception of the next impulse from the master clock.
III.6 Installation on a DHF network The first time you switch it on, you must set the clock to INIT mode (see page 29) in the technician menu. INIT mode enables matching with a master clock which is itself in INIT mode. It switches to normal mode automatically on reception of the time from the master clock, memorising the address of the transmitter.
III.7 Installation on an NTP network An SNTP server periodically transmits the UTC time on the Ethernet network. The clock automatically sets itself to the right time after receiving several coherent time messages and applying the time zone configuration. The NTP server must have a transmission (Poll) period of less than 128 seconds. Make the connections directly on the terminal strip as shown in the diagram below or use the adapter supplied enabling connection on an RJ45 connector.
III.8 Installation on an RS232/RS422 ASCII network For an ASCII network, there are two possible choices: RS232 and RS422. For RS232, all the DIP switches are down. For RS422, all the DIP switches are up. Connect the cable as shown in the diagram below. Ground Ground Nota : Do not forget to select F into the prog/alternate menu in order to validate and...

III.13 Configuration of DIP switches The DIP switches are set in the factory, but it may be useful when installing several HMT clocks in series to configure DIP switches 3 to 5. Clock type Dip 1 Dip 2...
III.15 Matching of an HF remote control For the HF remote control to function with the HMT Led clock, matching must be carried out. This operation is carried out in the factory. Matching is carried out on switching on of the clock for a limited period of 30 seconds, by pressing the [T] button for at least 1 second.

[Sel] pushbutton (inside clock only) - Long press (1 second) to access the programming menu (Time/Prog/Tech/ Test). - When in a menu, long press (1 second) to exit from the menu. - Short press to validate the previously selected menu or parameter. [S] pushbutton (HF remote control only) - In a menu, press briefly to exit from the menu.
IV.1 Main menu The main menu allows you to access all the HMT Led readout adjustment functions. It contains 6 menus (the CHRO and INFO menus exist only with the HF remote control) : CHRO : used to program the timing functions.
IV.2 CHRO menu: count-up and count-down setting Enter the CHRO menu (see page 15). A message flashes (“up”, “down”, “day up” or “day down”). Modify with the [R] button. “Up” starts timing in count-up mode, “down” starts timing in count-down mode and “day” starts a countdown in days.

IV.8 Displaying a numerical value A numerical value can be displayed by selecting alternation “F” in manual mode or via a PC serial link. Note: if both input modes are used (manual and via serial link), the value actually displayed will always be the last value entered. Note 2: additional instructions are enclosed in the packaging for entering values via a PC serial link.
V - Types of time synchronisation Independent mode “Ind” • The clock is totally independent; it receives the time information from its own time base. FI or DCF radio-synchronised mode “rAd” • The clock is independent; it receives the time information from its time base which is corrected in the event of deviation by comparing it with the signal from the FI or DCF transmitter.
