This button functions only in the run mode. When the
Setpoint/Alarm features are unlocked, pressing this button
sequentially recalls the previous setpoint settings to the display.
After the ‘MIN’ and ‘MAX’ buttons are used to alter those
values as desired, pressing the ‘SETPTS’ button, again, stores
these new values.

Unless the ‘SETPTS’ button is pressed, each of the four setpoint
values is displayed for approximately 10 seconds after the last
press of the ‘SETPTS’ button. Holding the ‘SETPTS’ button
depressed stalls this automatic sequence, retaining the most
recent setpoint number on the display.

ITEM DESCRIPTION

4  /MAX BUTTON

During run mode, pressing this button displays the “HI RDG”
(peak reading) value that has occurred up to the moment the

‘MAX’ button is pressed. This peak reading flashes, to

distinguish its value from the current readings. Since this is a
dynamic peak reading, the value will change if the value
increases while reviewing it.

To return to display of the current readings without resetting the
peak-value memory to zero (0), press the ‘MAX’ button once
again.

To reset the peak-value memory (start a new peak determining
period), press the ‘RESET’ button once.

During the configuration mode, the ‘MAX’ button is used to
change the numerical value of the flashing digit displayed. For
submenu items, such as “L1C.1=0”, pressing the ‘MAX’ button
toggles the choice from “0” to “1”.

The meter allows rapid changes of a displayed numerical value
by making “0” the first value to occur when the ‘MAX’ button is
pressed. After that, the numbers increase to “9” and then roll
over to “0” again. A negative (“–”) symbol may be displayed in
the most significant digit (i.e. the digit at the far left such as
shown here “–.8.8.8.8.8.”)

In the SETPT (SETPOINT) mode (SP1, SP2, etc), pressing the
‘MAX’ button causes the flashing digit to increment by 1 from 0
to 9.



/MIN BUTTON

During run mode, pressing the ‘MIN’ button recalls the “LO
RDG” (valley reading) measured since the last press of the
‘RESET’ button. This lowest value flashes, to distinguish it from
the current process display. Since this is a dynamic valley
reading, the value will change if the value decreases while
reviewing it.

ITEM DESCRIPTION

To return to the actual process display, without resetting the low­value memory, press the ‘MIN’ button once again.

To reset the memory for current-value readings (start a new
observation period), press the ‘RESET’ button once and the
meter will return to the run mode.

In the configuration mode, once in a submenu (like input type)
the ‘MIN’ button allows you scroll through the available choices
such as, 0-20 mA or 4-20 mA, etc.

In the SETPT mode, the ‘MIN’ button advances the flashing digit
to the right.

6 MENU BUTTON

In the run mode, this button terminates the measurement
process and allows you to enter the configuration mode,
advancing through the configuration menus.

In the configuration mode, this button will store changes in the
non-volatile memory at the same time advancing the display to
the next menu item.

7 RESET BUTTON

In the run mode, pressing the ‘RESET’ button once erases the
memories of peak (“HI RDG”), valley (“LO RDG”), and ALARM
latches. The display then returns to the run mode.

WARNING: Pressing the ‘RESET’ button two (2) times will
result in a hard reset of the meter. This will clear the Peak &
Valley, Alarm latches and meter reading and immediately begin
a new measurement.

In the configuration mode, pressing the ‘RESET’ button once,
displays the previous selection. For example, if you were in
“IN CNF” then pressed the ‘RESET’ button once, the display will
then show “RD.SC.OF”. Press the ‘RESET’ button two times to
return to the run mode.

5.1 CONDITIONS REQUIRING DISASSEMBLY

You may need to remove the sleeve or open the meter for several reasons:

1. To inspect the rating label on the case (not the same label as on the
sleeve) (Section 5.2.1).

2. To check or change the 115 V ac or 230 V ac or main board jumpers
(Sections 5.2.2 and 5.2.4).

3. To install optional output board(s) (Section 5.2.3).

4. To mount the meter in a panel (Section 5.2.5).

5.2 ASSEMBLY/DISASSEMBLY OPENING

OPENING THE METER

Your meter is fully assembled, but not wired. See Section 7 for wiring
connection for power and sensor inputs. In most cases, if you have ordered
optional boards with the meter, these boards will already be installed.

You will need to remove only the rear cover to complete wiring, but you will
have to open the meter to do one or more of the following:

WARNING!: You must disconnect and turn-off the power and connector
signals before accessing the unit and installing optional boards. Failure to do
so may result in injury!

a. Check or reconfigure the Transformer Jumpers on the Main Board so

that they correspond to your line voltage (W1 and W2 for 115 V ac, or
W3 for 230 V ac). See Section 5.2.2.

b. Install optional boards. See Section 5.2.3.

c. Access jumpers on the Main and optional boards. See Section 5.2.4.

5-1

Setup

Figure 5-1. Meter Exploded View

Using Figures 5-1 as a guide, follow these simple instructions to open the
meter:

IMPORTANT: Turn-off the power and input signals from the unit before
proceeding. Failure to do so may result in injury!

1. Remove the cover mounting screw that secures the rear protective cover
to the meter, and remove the Rear Protective Cover.

If you are simply wiring the meter–but not checking jumpers or installing
or removing boards–this is as far as the meter needs to be
disassembled. Go to Section 5.2.1.

2. Remove all wiring connectors from the rear of the meter.

3. Remove the two thumbnuts that secure the case to the sleeve.

4. Remove the sleeve completely by sliding it back from the front bezel.

To look at the Rating/Product ID label on the case, you must follow the first
step as described in Section 5-2. Refer to Figure 5-2 for the location of the
Product Identification label.

The meter is protected in accordance with Class I of EN61010. Refer to
Safety Considerations page.

WARNING: If your meter is to be wired to sensors to control inputs that
could be hazardous potentials, these potentials will be carried to the 20-pin
output connector (P2) at the rear. They will also be present on the meter’s
circuit boards. Follow all instructions carefully BEFORE connecting the
meter to any source of power.

DO NOT contact any exposed metal parts, install optional board(s), change
jumpers, or in any way disassemble or assemble the meter while it is
connected to AC voltage.

Note the following information and guidelines for safe operation of your
meter:

Power Voltage

Your power source voltage rating should agree with the voltage under which
the meter has been configured to operate. The first thing you should do is
verify this.

The meter’s operating voltage is shown in the VOLTS: entry of the Product
Identification and Serial Number Label. It is located on the case, as shown in
Figure 5-2, and is clearly visible on the meter packing box.

5.2.2 Main Board Power Jumpers

To check voltage jumpers or to change from 115 V ac to 230 V ac:

CAUTION: The meter has no power-on switch; it will be in operation as soon
as you apply power. To change the factory preset jumpers, disconnect the
power from the unit. Failure to do so may result in injury! The jumpers must
be changed by specifically trained personnel.

1. “Reveal the Main Board” (refer to Section 5.2, Disassembly).

2. Locate the main board assembly and position it in front of you the same
way as shown in Figure 5-3.

3. On the main board, locate the transformer jumpers W1, W2, and W3
near the transformer T1.
If your power requirement is 115 V ac, jumpers W1 and W2 should be
installed. (DO NOT INSTALL W3)
