CAUTION
!
All electrical wiring must be in accordance with all local state and national
codes that apply.
Do not exceed the rated current of the D.C. power supply (100MA) or the form
’C’ relay outputs (5A/240VAC resistive).
WARNING
Hazardous voltages are present within the enclosure. Installation or service
should only be carried out by trained personnel.

PROGRAMMING SETUP
Review Screens
The 700 Series MM utilizes ‘plain English’ menu driven screens hich are sequential and intuitive.
When the unit po ers up, the startup screen ill appear as follo s:
After the initial screens have appeared, the unit ill sho the ‘MAIN SCREEN’ hich scrolls as

NOTE: Should any channel go into “WARN’ or ALARM modes, screen will continue to
scroll with the alarm message on the bottom line and the WARN and/or HIGH temperature RED
LED(s) will be lit.

PROGRAMMING SCREENS
From the Main Menu, Press the  button to access the Pass ord Screen:
.
Use the   buttons to enter the preprogrammed pass ord, then press  to advance to the Menu
Screens.
Use the  buttons to advance to the ‘Scaling’ screen.
NOTE: Since the unit is designed for a fixed range sensor scaling is automatic. Ho ever due to
inconsistencies in some sensors a ‘TWEAK’ screen is provided to make minor adjustments.
Use a RTD simulator to inject a kno n temperature value into each channel and use the buttons to
make the screen value match the injected signal.
Press the  button to advance through all input screens and hen complete the controller ill save all
changed values.
And return to the Main Screen.

This completes the ‘Scaling’ section. Press  to save any changed values and return to the ‘Main Menu’
Screen. As previously described, enter the MENU selection and select the ‘SETPOINTS’ menu, here
process setpoints are entered. The first screen is the bearing arning setpoint.
Use  to change or press  to advance to the: Bearing Setpoint Screens.
Use  to change or press  to advance to the: Winding Setpoint Screens.
Use  to change or press  to advance to the:
Press the  to save values and return to the ‘Main Screen’.
This is the temperature hich
brings up the ‘HOT’ alarm and
turns on the ‘Warn’ LED and
relay output.
This is the temperature hich
brings up the ‘VERY HOT’
alarm and turns on the
‘Alarm” LED and relay
output.
This is the temperature hich
brings up the phase ’HOT’
alarm and the turns on the
Alarm LED and the relay
output.
This is the temperature hich
brings up the phase ‘VERY
HOT’ alarm and turns on the
Alarm LED and the relay
output
.

ADVANCE TO THE ‘SETUP’ MENU’
Setup screen provides ‘global’ parameters hich affect overall performance and operation.
PASSWORD SCREEN
Setting a pass ord ‘Locks’ out unauthorized access to program items. NOTE: Please make a note of
the password value if changed. Access to the Menus will be unavailable without the correct
password.
Press  to advance to the clock/calendar settings.
Use the  buttons to change the month. Press  to advance.
Use the  buttons to change the year. Press  to advance.
Use the  buttons to change the other settings as previously described.

11
Press  to advance to the log interval time settings.
NOTE: This screen allo s for setting the log interval. As sho n the unit ill take a reading every 5
seconds.
Logging may also be started and stopped by connecting a dry contact bet een DI1 and digital
common. It is necessary to remove the screen panel to access this terminal block. Logging
occurs henever these points are closed.
THE DIAGNOSTIC SCREEN
The final menu item is ‘DIAGNOSTICS’. This screen provides real time information about the current
status of both inputs and outputs.
NOTE: Only digital input (1) is used in the 700MM.
This is the Relay
Output status.
Sho n is Relay
1 and Relay 2
Active. The 8
inputs are sho n
the same ay.

• DISPLAY REMAINS AT ZERO OR SHOWS NO CHANGE -- If the display remains at zero or
sho s no change but the process is changing, check for DC voltage on the loop. With 2 ire (4/20MA)
instruments check ith a DC voltmeter at the level instrument, by disconnecting the level instrument
from its 2 ires and measuring across these 2 ires ith a DC voltmeter for the presence of 24VDC.
Check the diagnostic screen for analog input value.
If DC voltage is present, reconnect the negative ire of the supply and insert a milliamp meter bet een
the positive ires. The loop should provide a signal bet een 4 and 20 MA. If no current is present
or & current exceeds 20MA consult the level instrument supplier.
If DC voltage is not present check the user supplied po er supply or if using the 700 DPCF/TPCF supply
measure across terminals 24VDC and + and -. If no 24VDC is present consult factory. If 24VDC is
present check field iring bet een the 700 DPC and the field device and recheck ‘SCALE’ functions to
ensure correct setup.
NOTE: This should be done by using the user provided circuit breaker or fuse,
not by removing the power wires at the terminal block. Serious injury or death
can occur if contact is made with the incoming AC power.
MAINTENANCE AND TROUBLE SHOOTING
The Series 700 MM is a digital solid state device hich requires no periodic maintenance.
Occasional checks of the unit should be carried out for physical and mechanical security of mounting,
terminal blocks, and electrical iring.
TROUBLE SHOOTING
• UNIT ‘LOCKS UP’ -- Recycle po er to the unit by removing AC po er, aiting 10 seconds and
reconnecting po er.
