1.2 Installation
1.2.1 Torque specifications
There are four sizes of strain reliefs exiting the indicator: PG11, PG7, PG13.5 and NPT
3/4”. The torque specifications for the locknuts which hold the strain reliefs to the
indicator housing and the specs for the dome nuts which seal the cable that passes
through the strain relief are shown in the table below.
1.2.2 Proper grounding of cables
On the stainless steel desktop models, cable shield wires should be grounded directly
tothestuds providedat the bottomoftheenclosure,closeto thestrainrelief entrypoint,
with wire lengths at a minimum. On the aluminum and panel mount models the shield
wires should be connected to the SHLD connection on the corresponding terminal
block connectors.
NO USER SERVICEABLE PARTS. REFER TO QUALIFIED SERVICE
PERSONNEL FOR SERVICE.
CAUTION: The acorn nuts holding the back plate of the indicator in place must
each be tightened, in multiple passes, in the following pattern to a final torque
of 0.68 N-m (approximately 6 in-lbs) to ensure proper gasket sealing.

1.2 Installation
1.2.3 Panel mount scale interface cable installation
The ZM401 & ZM405 Panel Mount assemblies include the AWT25-501388 Ferrite.
Installing the Ferrite on the Scale Interface Cable on the Panel Mount models assists
with eliminating potential noise captured by the scale interface cable.
Attach the ferrite onto the scale interface cable by wrapping the unshielded wires once
around the ferrite as shown below. Leave the Shield drain wire outside the ferrite and
connect to the SHLD connection on the terminal block, as shown in the photos below.
The optional 2nd Scale Input 5VDC & 10VDC Excitation Modules also include the
AWT25-501388 Ferrite for use on the ZM401 & ZM405 Panel Mount Models. The
Ferrites are not needed on the stainless steel desktop models as the Shield of the
Scale Interface cable terminates directly to the studs on the bottom of the enclosure.

1.2.4 Safe handling of equipment with batteries
1.2.5 Wet conditions
Under wet conditions, the plug must be connected to the final branch circuit via an
appropriate socket / receptacle designed for washdown use.
Installations within the USA should use a cover that meets NEMA 3R specifications
as required by the National Electrical Code under section 410-57. This allows the unit
to be plugged in with a rain tight cover fitted over the plug.
Installations within Europe must use a socket which provides a minimum of IP56
protection to the plug / cable assembly. Care must be taken to make sure that the
degree of protection provided by the socket is suitable for the environment.
1.3 Routine maintenance
Always turn off the machine and isolate from the power supply before starting any
routine maintenance to avoid the possibility of electric shock.
CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer. Dispose
of used batteries according to the manufacturer’s instructions.
ATTENTION: Il y a danger d'explosion s'il y a remplacement incorrect de la
batterie, remplacer uniquement avec une batterie du même type ou d'un type
équivalent recommandé par le constructeur. Mettre au rebut les batteries
usagées conformément aux instructions du fabricant.
IMPORTANT: This equipment must be routinely checked for proper operation
and calibration.
Application and usage will determine the frequency of calibration required for
safe operation.

2.2 Powering up the ZM400
2.2 Powering up the ZM400
The indicator is always active as long as power is received. Power can be supplied by:
lAC power cord connected to a properly grounded outlet (100VAC - 240 VAC,
50 or 60 Hz)
lExternal 12VDC @ 1.2 Amps up to 36VDC @400mA (14.4 Watts). These are
the power requirements for a fully loaded unit (16 x 350 load cell, 500mA out
the 5V COM port terminal block, 500mA load on USB Host, and Wireless
option card installed).
lAC to 24VDC power converter (optional accessory for panel mount version)
lOptional external battery pack with 4 D cells:
1 x 350 ohm load cell = 6 hours battery life
4 x 350 ohm load cell = 4 hours battery life
8 x 350 ohm load cell = 1 hour battery life
(See D-cell Battery pack option (AWT05-505852) and external battery
circuitry on page 148 for more information.)
2.3 Alphanumeric entry procedure (ZM401 only)
The keys in Figure 2.2 have alternate functions in alphanumeric entry screens.

Usethekeys,asdescribedinFigure 2.2,toenteranalphanumericvalueon thedisplay.
For alphanumeric menu entries the graphics display will only show the last six
characters entered. Following is an example:
Example: To key in ZM4:
Repeatedly press the TARE()or SELECT()key until Zappears on the display.
Press the UNITS()key once to move cursor one space to the right.
Repeatedly press the TARE()or SELECT()key until Mappears on the display.

Repeatedly press the TARE()or SELECT()key until 4appears on the display.
Press the ZERO key to enter or accept the value.
Press the PRINT()key to move the entry function one digit to the left. This effectively
deletes the current value in that position and allows you to enter a new value in that
position.

2 Introduction
2.4 Using the alphanumeric keypad (ZM405 only)
Use the alphanumeric keypad to enter numbers and words when prompted by the
indicator. For alphanumeric menu entries the graphics display will only show the last
six characters entered.
The action is similar to using a cell phone to select the number or letter. A rapid
succession of presses will scroll through the number on the key and then the letters,
starting with upper case and then lower case. The decimal key scrolls through the
negative sign, pound sign, colon, comma and percent sign. The 0key toggles between
0 and a space.
2.5 Entering negative numbers or decimal point
To enter a minus sign for a negative number or a decimal point (or comma), press the
Ckey (or PRINT key) to clear the current value from the display.
Then to enter a negative number, with a single 0displayed press SELECT. The first
character will then change to a (-) negative sign. Enter the rest of the digits normally.
To enter a decimal point (or comma), on a ZM405 use the decimal point key. On a
ZM401 when the flashing digit is a 0 press the SELECT key and a decimal point (or
comma) will appear. Then press the UNITS key to scroll in the next digit to follow the
decimal and enter the rest of the digits normally. To enter a value less than 1 requires
the entry of the leading 0 before a decimal point is allowed.
2.6 String index/character data entry
Below are guidelines to create or edit text and scale information for print formats. This
is a sample of a string entry display.
Left-flashing bar graph segments indicate you are in the String Index select mode. Use
the Table 1 key legend to:
lmove to the index number you want to edit

When these segments
are flashing, you are in

ZM400 Series Indicators Service Manual 20
3 Introduction to the menus
Menus, accessed through passwords, are available in the indicator to customize and
configure the indicator for your purposes. The menu levels and their passwords are
shown below:
Some menus appear in more than one menu level. As you can see in the table above,
the 111 password gives you access to three menus; User, About and Audit. The 3570
password gives you access to those three plus the Diagnostics menu. The 3088
password gives you access to those four plus the Setup menu.
This allows the supervisor to control access to some or all of the menus based on the
passwords shared. The menus are the same no matter which menu level you access
them from.
See Alphanumeric entry procedure (ZM401 only) on page 17 for instructions on how to
enter a password to get to the menus. Key functions in the menus are shown below.
Menu Navigation Keys:
Password Menu Level Accessed Menus
111 USER User, About, Audit
3570 DIAGNOSTICS Diag, User, About, Audit
3088 ADMIN Setup, Diag, User, About, Audit
2580 CALIBRATE Calib
1793 SUPER Application specific items. See User manual.
The CALIBRATE menu level accesses the calibration procedure only. You can also
access the calibration menu through the Setup menu using the ADMIN password.
The menus are always explained in a sequential manner to cover all information in a
logical fashion. You will probably never access all the menu items in this manner. You
can navigate to the area of the menu that needs to be changed by using the menu
maps and key navigation legends which are inserted as a reminder with most menus.
