Error Codes

Some DataTime

®

 displays have their own built-in troubleshooting mechanism. Failures that occur in the 

display driver use codes. If a display malfunctions, a failure code registers by showing an Ex value on the first 
two digits of the display. E indicates an error, and x represents the code number. Refer to the following table 
for a description of each failure code and for possible solutions.

Note: 

The LCD screen on the DM-100 controller will not show the following failure codes. Failure codes are 

only shown on the DataTime

®

 display.

Power On Self-Test

A useful troubleshooting tool is the power on self-test the host driver performs every time it powers up:

•  If the signal wiring between each controller is 

correct, the first two digits of each driver display 
Ad momentarily, and the first digit flashes three 
numbers indicating the decimal address set with 
the address switch. (If a client driver display’s 
A <number>, followed by P <number>, it is not 
receiving signal in, and is performing its own self-test.) 

•  The first two digits of each line display Lx, where x is the line number that the driver is set to control 

using the address switch (set with address plug on older drivers). 

•  Each line displays 1234… according to the column number of each of its digits. Every line should 

show 1 on the left-most digit, and all digits should be numbered consecutively from left to right. 
If this is not the case, either the wrong address is set, or the driver or digit harness is connected 
incorrectly.

If no address is set on the host driver, it will display E5, and all client drivers will continually cycle through 
the power on self-test.

Failure Code Description

Possible Solution

E1

Protocol Setting Error:

 There is an unsupported 

driver protocol setting.

Check the value set in the protocol plug of the 
driver (J20).

E2

Time Error:

 No valid time is stored in the driver; it 

may be a failure of the real-time clock on board or 
other timekeeping device.

Set the time in the display using the 

Set Time

 

menu option on the DM-100 controller.

E3

Temperature Error:

 No response coming from 

the temperature sensor, or general temperature 
sensor failure.

Check the temperature sensor location and verify 
all connections. Refer to 

Section 2

 for wiring 

information.

Note: 

The temperature sensor takes about 10 

seconds to initialize on power up. The display 
shows this error until initialization is complete

If a temperature sensor is not used, set the hold 
time to zero.

E4

No Message Error: 

This code is shown when no 

messages are downloaded to the display

Download a new message to the display using 
the 

DISPLAY SEQUENCE

 key on the DM-100 

controller.

E5

No Line Number Selected Error:

 The driver for 

this line has a Protocol-4 plug installed in J20, but 
the address is not set on the address switch.

Set the line number by setting the address 
using the address switch. The Protocol-4 plug 
designates this driver as the “host.” If this is not 
the host, remove the Protocol-4 plug from J20.
