5.3.5 TEST 5 - KEYPAD/DISPLAY TEST
This test allows the operator to verify that the keys work and that all display elements can be
lighted. No special test equipment is required for this test. With tSt5 displayed press and
hold the DOWN key then press the SCROLL key. The display will go blank. Release both
keys, then press each key to be tested.

UP KEY uAro
DOWN KEY dAro
UP AND DOWN KEYS ALL LED’s AND SEGMENTS LIGHTED
To exit Test 5, press the SCROLL and UP key simultaneously. tSt5 will be displayed.
5.3.6 TEST 6 RELAY/SSR DRIVER OUTPUT TEST
Verifies that the Relay/SSR Driver output(s) are working. A volt/ohm meter will be useful to
verify the output opertion. With tSt6 displayed press and hold the DOWN key then press the
SCROLL key. oFF will be displayed. For SPST relay outputs, connect the
volt/ohm meter, set to ohms, across the relay outputs. For SSR driver outputs, connect the
volt/ohm meter across the output terminals in the volt/DC mode. Depress the DOWN key
repeatedly to advance through the following sequence:
DISPLAY RELAY ON
rLYA A Only
rLYb B Only
rLYC C Only
oFF None
The relays should be checked for continuity when on and high impedance when off. SSR
drivers will output 5 VDC when on and 0 VDC when off. This sequence may be repeated by
using the DOWN key. To exit press the SCROLL key and tSt6 will be displayed. The
existence of relay SSR outputs is dependent upon the hardware configuration.
5.3.7 TEST 7 - CURRENT OUTPUT 1 TEST
This test allows the user to verify that current Output 1 is functioning properly and will allow
the adjustment of the current output value for testing of associated equipment. A volt meter
with an appropriate shunt resistor or milliamp meter will be needed to execute this test. With
tSt7 displayed, depress and hold the DOWN key, then press the SCROLL key. Connect the
DVM or milliamp meter across the output terminals 5 and 6. The display will indicate 4
milliamps output. Use the UP and DOWN keys to vary the output in 1mA steps. The current
output reading should be
±
0.5mA at any output value. To exit the test, press the SCROLL
key and “tSt7” will be displayed. The existence of the mADC current output is dependent
upon the hardware configuration as indicated by the model number.
5.3.8 TEST 8 - CURRENT OUTPUT 2 TEST
This test is the same as Test 7 except for Output 2. Check the output at terminals 7 and 5.
