The front panel displayed is referred to as the “Home or Run” Screen.
Overview: Front Panel displays, and indicators.
1: CH1 & CH2 Inc/Dec LED’s. Indicate “ON/OFF” Time Proportioned output.
INC, up arrow (heat, humidify, climb, etc.) and DEC, down arrow (Cool, de-humidify, dive, etc.)
2: Displays Program # (1 – 99), Step # (1 – 200), and Time Remaining in current program step.
3: Displays Interface, LCL (Local, front panel) or RMT (Remote, external computer) and Mode
(RUN, STP, EOP, GS1, GS2, etc.)
4: Line 1: Displays CH1 & CH2 SP (Setpoint) and status of first eight event outputs (1 – 8)
Line 2: Displays CH1 & CH2 PV (Process value) and status of next eight event outputs (A – H)
(SP and PV are displayed in units configured for that channel (deg C, F, %RH, Alt/FT etc.)
5: ALM – 4 possible flashing displays: S1 – S2 – L1 – L2.
S1 & S2 – Setpoint Alarm. Setpoint is out of configured controller span or input is open.
CH1 or CH2 PV will display “RANGE” setpoint out of range or “P.OP” – Probe Open.
L1 & L2 – DEV Limit Alarm. Channel is out of programmed +/- DEV span.
Each channel can be configured for the program to continue running or stop during alarm,
and for the alarm display and output to reset manually or automatically.
CH1 & CH2 share a common Logic low output from the 620A.
Overview: Front Panel Keypad.
NOTE: Keypad is fully functional for entry or
change only in the LCL mode.
Screens can be viewed but parameters
can not be changed in RMT mode.
RUN: Push to run a new program or resume a program after the Stop/Hold button is pushed.
STOP/HOLD: STOPS the running program and HOLDS the parameter values, Setpoints, Events and Time.
Push RUN to resume operation or RESET to reset current program back to step # 1.
RESET: In STOP (STP) mode resets program pointer to step 1 of selected program.
Returns display to the “HOME/RUN” screen from “any” screen or menu selection.
If the operator is on a screen they do not recognize or are unsure of, it is recommended to push
RESET. This returns to the HOME/RUN screen and allows access to the Main Menu
Pushing any other button could result in changing an operating parameter.
HELP: Not much is available.
PAGE UP: Moves to previous page of menus, configurations, editing, calibration, PID tuning, etc.
PAGE DOWN: Moves to next page of menus, configurations, editing, calibration, PID tuning, etc.
In LCL_STP mode of the Home/Run screen, pushing Page Down accesses the Main Menu.
SEL: Used to scroll through selections of a field on a page.
CLR: Clears the value or selection of the selected field on a Page.
ALPHA NUMERIC: Used for entering numeric data or selecting lettered events.
Cursor must be in the letter event field to select letter events.
ARROW KEYS (Up, Dn, Right, Left): Used to navigate cursor to different fields on a Page.
ENTER: Enters value of current filed and advances cursor to next field on the Page, or to the next
Page if entering from the last field on that page.
EDIT ONLY KEYS:
DUP STEP: Insert a step into the next location and copy current step information. All following steps advance x1.
CLR STEP: Clears all information in the current step to default values.
INS STEP: Insert a blank step into the next location. All following steps advance x1.
DEL STEP/PRG: With cursor over step number deletes the step. All following steps move back x1.
With the cursor over the PRG number the entire program is deleted from memory.
Examples: Advance x1: Steps 3 now 4, 4 now 5, etc.. Back x1: Steps 3 now 2, 4 now 3, etc.

Alarms Listings – What Alarms show Up
P.OP - Probe Open:
The control channels probe is disconnected, is defective, or has an open junction.
The control channel will read properly when the problem is corrected.
P.OP ACTION:
The PV field of the control channel will display P.OP and the controller INC and DEC
outputs will be disabled.
A running program will freeze. The time, events and unaffected control channel will
hold at their current values.
The program will resume operation when the problem is corrected.
RANGE (S1 OR S2):
The entered setpoint is outside the range allowed by the controller’s span.
Enter a valid setpoint or reconfigure the controllers span.
Note:
Changing the controller span is not recommended unless the attempted setpoints
are valid and within the prescribed range of operation.
Prior to changing the controller span, record the channel’s PBAND setting in the
PID tuning section. After the new span is entered, return to the PID tuning
section and enter the previously recorded PBAND value.
Do not change the PGAIN value. It will automatically adjust to the proper value.
RANGE ACTION:
The PV field of the control channel will display RANGE and the controller INC and DEC outputs will be
disabled.
A flashing S1 (CH1) or S2 (CH2) will be displayed in the ALM field of line 4 on the Home (Run) screen.
The “COMMON DEV ALARM” output on TB1-7 will go low.
A running program will freeze. The time, events and unaffected control channel will hold at their current values.
The program will resume operation when the problem is corrected.
DEVIATION (L1 OR L2): Programmer or Manual Modes.
The DEV is entered as a parameter of a program step or in the Manual Mode.
The DEV alarm function tracks the SP vs PV error.
If the PV is outside of the +/- range entered for the DEV the following actions occur.
DEVIATION ACTION:
A flashing L1 (CH1) or L2 (CH2) will be displayed in the ALM field of line 4 on the Home (Run) screen.
The “COMMON DEV ALARM” output on TB1-7 will go low.

PROGRAMMER CONFIGURATION AND RESPONSE TO DEVIATION ALARM:
The response to a DEV Alarm is independently configured for each channel In the
Model 620A’s programmer configuration section.
PROGRAMMER ACTION:
Stop during DEV: The programmer stops when a deviation conditon is
detected. The time display stops decrementing, the controller setpoints
and event outputs are latched.
The controllers continue operating and maintain the latched setpoints.
The alarm field display flashes and the alarm output TB1-7 goes low.
Run during DEV: The programmer continues to run.
The alarm field display flashes and the alarm output TB1-7 goes low.
ALARM RESET ACTION:
AUTOMATIC: If Stop during DEV is selected. The Model 620A will
automatically resume operation. The alarm display and output will be
automatically reset as soon and the out of limits condition has ended.
If Run during DEV is selected. The alarm display and output will be
automatically reset as soon and the out of limits condition has ended.
MANUAL: The reset action occures “only” when the out-of-limits conditon has
ended and the Model 620A RUN mode is enabled.
The Run mode is enabled by pushing the Front Panel <RUN>, providing
a run signal from the photoisolated Run input or issuing a Run command
via the computer (in RMT mode only).
STOP SCREEN
Pushing the <STOP/HOLD> button from the LCL_RUN screen will freeze the time, hold all operating
parameters at their current values, and display STP in the Mode Field.
