1 Introduction
General description
This manual contains information for the installation and operation of the the LD5-TR Monitor. The
instrument may be set to operate as a ratemeter or totaliser or allow toggling between rate and total
displays. A “grand total” display is also viewable and can be separately reset. The OPEr function allows
selection of one of these three modes. A brief description of each mode is given below. The “Explanation
of functions” chapter details functions available for all modes, consult the separate function table for each
mode to view the available functions for these modes.
The three modes of operation relevant to this manual selectable at the OPEr function are:
1. totL - totaliser/counter display. The input pulses are totalised, scaled in engineering units and
displayed e.g. Total litres, mm etc. Count up or count down is possible. A total and grand total may
be viewed and reset separately. The grand total is a separate total memory which allows storage of
all the previous totals.
2. RAtE - frequency/rate display. The frequency or rate of the input may be scaled in engineering
units and displayed e.g. R.P.M., Bottles/min., Litres/hour etc.. For low frequency inputs (input
always below 1kHz) there is an option of displaying either rate or period. For frequencies below
1kHz there is a choice of displaying rate, averaged rate or period each of which are scaleable.
3. both - total/rate display (display may be toggled to either total or rate) This mode is primarily
used when the display is required to toggle between a rate and total display via an external contact
closure or via the front panel ^and vbuttons (only fitted on certain display options). For low
frequency inputs (input always below 1kHz) there is an option of toggling between rate/total or
period/total. A total and grand total may be viewed and reset separately.
Up/Down totalising
Input 2 can be set to control whether the pulses on input 1 cause the total to increase or decrease. The
IN1 dir display must be set to UP.dn for this input to be used. Input 2 type is configured by the IN
2group of functions.
1.1 Selecting and altering access levels
This subsection details the use ”access levels”. Access levels can be used to obtain easy access to functions
which are regularly required and to limit access to functions which are not required or which restricted
access is required. These access level settings can be ignored if no restrictions to access are required and
no easy access to selected functions is required.
Each setup function has a default access level allocated to it, for example the ascending alarm 1 function
AL.A1 is allocated a default level of 2. There is a facility for the user to change the access levels for a
limited number of functions to make them either easier to access or harder to access as required, see the
Fn.1 CodE function.
There are different ways of accessing setup functions, these are explained in the following section. Each
mode allows a selection of access levels i.e. allows some choice of which functions are accessible.
The access levels available are:
None - no access to functions
1- access to functions allocated to level 1
LD5TRMAN-1.7-0 3 of 72
2- access to functions allocated to level 2
3- access to functions allocated to level 3
4- access to functions allocated to level 4
5- access to functions allocated to level 5
6- access to functions allocated to level 6
CAL - access to all normal operation functions
1.2 Accessing setup functions
The setup functions allow adjustment of the instruments operation functions. There are five different ways
of accessing setup functions. Each mode allows a selection of access levels i.e. allows some choice of
which functions are accessible.
As as summary the methods available are:
•Easy mode - this is the easiest access mode simply requiring the Fbutton to be pressed for 3
seconds. This mode would normally be used to gain access to functions which require frequent
adjustment.
•Remote input mode - this uses the Easy method of access but also requires the use of a remote
input switch.
•PIN 1 mode - this method allows a PIN to be set with access via PIN entry.
•PIN 2 mode - this method also requires a PIN and would generally be use to allow a higher access
level than the first PIN.
•Super Cal mode - this method requires a power up procedure and will allow access to all functions.
These modes are explained in more detail below.
•Easy mode - Allows access to the level set by the EASY LEUL function in the ACCS menu. By
default the Easy access is set to NONE level i.e. no access.
The Easy mode simply requires that the Fbutton is held pressed until the message FUNC is seen
followed by the first function message, this should take approximately 3 seconds. If the message
FUNC End or no response is seen at this point it means that the access level has been set to NONE.
The default access for this level is NONE so the access level will need to be changed if access via
this method is required.
•Remote input mode - Allows access to the level set by the R.INP LEUL function in the ACCS
menu. By default the Remote input access is set to CAL level allowing access to all setup functions.
The remote input mode uses the same access method as the Easy mode but also requires that one of
the available remote inputs is set to ACCS and that the selected remote input is activated i.e. shorted
to GND. The default access for this level is NONE so the access level will need to be changed if
access via this method is required.
4of72 LD5TRMAN-1.7-0
•PIN 1 mode - Allows access to the level set by the USr.1 LEUL function in the ACCS menu.
The PIN 1 mode requires the Fbutton is pressed and released then within 2 seconds press the ^
and vbuttons at the same time. The PIN can be set via the Pin.1 CodE function in the ACCS
menu. A USr.1 LEUL setting of 0disables the PIN which means that there is no need to enter
the PIN. If the USr.1 LEUL function has been set to a number other than NONE then the first
function seen when entering via PIN 1 mode will be the function CodE. When this function is
seen the PIN value set at the USr.1 LEUL function must be entered via the ^or vpushbuttons
followed by pressing Fto accept the PIN before the user can progress to the setup functions.
•PIN 2 mode - Allows access to the level set by the USr.2 LEUL function in the ACCS menu.
This method uses the same access method as PIN 1 mode above. A Pin.2 CodE setting of NonE
disables the PIN. If the USr.1 LEUL or a USr.2 LEUL function has been set to a number other
than NonE then the first function seen when entering via PIN 1/PIN2 mode will be the function
CodE. When this function is seen the PIN value set at the USr.1 LEUL function can be entered
for access to the level set at the Pin.1 ACCS function or enter the USr.2 LEUL PIN to gain
access to the level set at the Pin.2 ACCS function. A correct code will allow access to the
functions at the selected level. An incorrect code will result in the FUNC End message being
seen indicating that access to setup functions has been refused and the display will return to normal
measurement mode.
•Super Cal mode - This method can be used to gain access to all functions. If a PIN has been set and
forgotten use this method to access the PIN functions to check the settings. To access via Super Cal
mode with the instrument switched off hold in the Fbutton whilst the instrument powers up. Keep
the button pressed until the S.CAL message is seen, you can then release the Fbutton. Next press
and release Fthen within 2 seconds press and release the ^and vpushbuttons simultaneously.

The setup functions are organised in blocks or sections e.g. all the settings for channel 1 alarms are in
the AL1 section. Once access to setup functions has been gained use the ^and vbuttons to select
the section required then press Fto enter this section and again us the ^and vbuttons to select the
required function for alteration and press Fto allow alteration of this function.

Error and warning messages
A message of -OR- can mean that the value to be displayed is too large a positive or negative a number
to be displayed i.e. a rate or total. If seen in a total display the total will have to be reset to zero or a preset
value to return to normal display. This message can also be seen in circumstances described below.
The visual alarm setting for rate and total RAtE dISP and tOt dISP can be programmed to show
visual warnings on the display of flashing the display value on and off or display shows ---- or -OR-
or -UR- or -HI- or -LO-. These warning messages indicate that the associated rate and/or total low
and high limit values have been exceeded.

3 Electrical Installation
The display is designed for continuous operation and therefore no mains/power switch is fitted to the
unit. It is recommended that an external switch and fuse be provided to allow the unit to be removed for
servicing. To install cables remove six front panel retaining screws. Remove front panel taking care not
to damage the ribbon cable (ribbon cable joins the front display circuit board to the main circuit board).
Connect power and input cables to the plug in terminal blocks located within the enclosure. The terminals
are clearly labeled and unplug for ease of installation, please take care to connect them correctly. The
terminal blocks allow for wires of up to 2.5mm2to be fitted (relays and power) and 1.5mm2for inputs.
When power is applied the instrument will cycle through a display sequence, indicating the software
version and other status information, this indicates that the instrument is functioning.

3.5 Input connections
The display will accept many common input sensor types. The input circuit is configured by the IN1
and IN2 functions. Input 1 is the rate/total pulse input and input 2 can be used to control if the pulses
sent to input 1 will cause the total to count up or count down i.e Up/Down count control (requires tOt
dir function to be set to UP.dn). The common input types together with typical IN1 settings for these
inputs are given below.

3.5.1 Remote/Digital inputs
The digital inputs will accept voltage free contact closure inputs or up to 24VDC signal. The electrical
configuration for these inputs is configured by digital input functions, see the d.in section functions. The
operation mode of the digital inputs are controlled by separate functions for each input, see the R.INP
section functions. The electrical configuration for these inputs is configured by digital input functions,
see the d.in section functions. Wiring example showing voltage free contacts below.
For reset and preset operation set the chosen remote input to RSEt or P.SEt as required.

The excitation voltage (can be set to 5, 12 or 18VDC if required) can be set at the P.out function. The
Up/Down direction input is only used when the IN1 dir function is set to UP.dn. If input 2 is set for
pull up then an open circuit on the direction will be count up when input 2 is open circuit and down when
it is short circuit. If input 2 is set for pull down then an open circuit will cause the display to count down
when it is open circuit and down when it is short circuit.
