■ CAUTIONS !

• Hold the PU-2A securely in your hand when programming.
Never hang the PU-2A unit by the connection cable. Vibration and physical impact by dropping the PU-2A could

cause malfunction of the unit.

• Quick change of ambient temperature and humidity, from low temp. place to high temp. and humidity, could cause

condensation, which may destroy electronic circuitry in the PU-2A.

• Use the PU-2A in ambient temperature: 0 – 45°C.

PU-2A USERS MANUAL EM-9255-C Rev.14

A-1. INTRODUCTION

The fundamental procedures required for conguring input data of the M-System JX series eld programmable signal

conditioners are explained in this section. In order to do this, the Model PU-2A programming unit is required.

Each function is easily programmable via the PU-2A keyboard by selecting a specic number ([DATA] entry for each
[ITEM]) from the table of the specic unit function. The operator need only understand the meaning of each [ITEM]

in order to program the unit. No special programming skills or software is required.

There is specic terminology associated with the PU-2A programming unit. The table categories are called [GROUP],

which define whether the data is common for many types of transmitters or inherent for each transmitter model.

Each group has several [ITEM] numbers, each of which shows what is to be programmed or monitored.

[DATA] is the
specic input value or percentage to be adjusted. The PU-2A programming unit’s operations are based on these three levels:
[GROUP] – [ITEM] – [DATA].

A-2. GENERAL OPERATION DESCRIPTION

■

DESCRIPTION

• When You Want to Monitor the Transmitter Status in Operation:

1) Be sure that the power is supplied to the transmitter.

2) Connect the PU-2A to the transmitter via the front modular jack.

3) Specify an item to be monitored.
Press [GROUP] NN [ITEM] NN. (N = number entry keys)

4) Specify another item if necessary. Repeat (2).

5) Disconnect the PU-2A.

• When You Want to Change Parameters:

1) Be sure that the power is supplied to the transmitter.

2) Connect the PU-2A to the transmitter via the front modular jack.

3) Switch the transmitter into PROGRAM mode with PU-2A.

4) Specify an item to be changed.

Press [GROUP] NN [ITEM] NN [DATA] N (NNN....) [ENTER] (N = number entry keys)

5) Specify another item if necessary. Repeat (3).

6) Disconnect the PU-2A.

■

MAINTENANCE SWITCH & OPERATION MODES

There are two operation modes for JX signal conditioners: MONITOR mode and PROGRAM mode. You use the Main­tenance Switch, lock command to prevent unauthorized access to specific data, for changing the operation mode.

In MONITOR mode, the signal conditioner is in normal operation, measuring, computing and outputting signals. You
can only monitor parameter settings, measuring result, output status but cannot affect the transmitter’s operation. No
parameter change except for the Maintenance Switch is available.
In PROGRAM mode, the transmitter stops measuring and renewing the output signal. The output signal is held, but
you can output a specic value for simulation and testing purposes. Parameter settings can be changed.
For changing to the PROGRAM mode, key in [ITEM] 01 [DATA] 1 [ENTER].

The display will appear as shown to the right:

When all the program changes are completed, disconnect the PU-2A. The
Maintenance Switch automatically defaults to “0” (lock position)*.
Do not turn on/off the power supply to the transmitter while the PU-2A is
connected. All memory will be lost if power is removed.

* For those models applicable to Section B, it is necessary to change the Maintenance Switch to MONITOR mode after pro-

gramming. All modication data will be lost if you unplug the PU-2A before returning to MONITOR mode. Read Section B.

NG MESSAGE

When there are errors in data entries, the PU-2A display indicates “NG”. Conrm the input data. Do not leave any
items in “NG” status, especially ITEM 10. If ITEM 10 is in “NG” status, all other ITEMs become unavailable. Be sure
to go through checking all ITEMs after ITEM 10 data entry.

■

OUTPUT SIMULATION PROGRAMMING

The output signal of the transmitter is held while in the PROGRAM mode, but you can output a specic value for
simulation and testing purposes. Press [GROUP] 01 [ITEM] 03 [DATA] (desired output value) [ENTER]. The output
value changes in accordance with further adjustments with other [ITEM]s.

• EXAMPLE: 50% output simulated for 1 – 5 V output range.

1 – 5 V range is converted into percentage against 0 – 5 V range with ITEM 3: 20 – 100%.

1) Be sure that the power is supplied to the transmitter.

2) Connect the PU-2A to the transmitter via the front modular jack.

3) Press [GROUP] 01 [DATA] 1 [ENTER].

4) Press [ITEM] 03 [DATA] 50 [ENTER].

5) Specify another group, item and data to cancel the simulated output.

6) Disconnect the PU-2A. (The simulated output is automatically cancelled.)

ROM VERSION INDICATION

PROGRAMMING UNIT

When the Programming Unit is connected with a JX transmitter (GROUP and ITEM indications are empty), press [#]
99 and display indicates the ROM version No. of the Programming Unit.

JX TRANSMITTER

Press [GROUP] 00 [ITEM] 99, and display indicates the ROM version No. of the transmitter.

WARNING!!
DO NOT TURN ON/OFF POWER SUPPLY TO THE TRANSMITTER
WHILE THE PU-2A IS CONNECTED. ALL MEMORY WILL BE LOST

IF POWER IS REMOVED.

The transmitter output signal is held when the PU-2A is connected.
It tracks the input signal only when the input or output monitor
command is entered.

GROUP NO. and ITEM NO. indication is clear.

• [GROUP] 00 : System Table. Clearing the data in the ROM.

Used when erasing segment data for a linearizer module.

• [GROUP] 01 : Used for entering input data for each transmitter.
Each table (GROUP) has a MAINTENANCE SWITCH ([ITEM]

01, lock command) to prevent unauthorized access to specic data.

• [ITEM] 01 [DATA] 0 : The transmitter input and output can be
monitored but cannot be programmed.

(display message = MTSW: MON.MODE)

• [ITEM] 01 [DATA] 1 : The transmitter can now be programmed.

(display message = MTSW: PRG.MODE)

To change the ITEM NO., press [ITEM] and then the number or
press the [UP] or [DOWN] key one or more times.

Press [DATA] and then the number required. When a wrong num­ber is typed, start again with the [DATA] key and input the correct
number.
The display goes back to the data indication state when [CLEAR]

is pressed.

Press [ENTER] to enter the data into the ROM. Programmed data

is again indicated on the display for confirmation.

Then proceed to the next ITEM NO. (Press [ITEM] and then the
number and repeat from Data Indication state.)

The transmitter output starts tracking the input signal.

The MAINTENANCE SWITCH automatically defaults to “0”
(lock position).

DO NOT TURN ON/OFF THE POWER SUPPLY TO THE TRANSMIT­TER WHILE THE PU-2A IS CONNECTED. ALL MEMORY WILL BE

LOST IF POWER IS REMOVED.

Be sure that power is supplied to the

transmitter.

Connect the PU-2A to the modular jack on
the front of transmitter.
Driving power for the PU-2A is supplied
from the transmitter.
