The HypotMAX also allow access to three MEMORY PROGRAMS through the remote
control connector. This gives the user the capability to quickly change parameters
and initiate a test remotely. The built in memory programs of the instrument are used
to accomplish this. Three internal memory programs can be accessed, by connecting
terminals 7, 8, and 9 in different combinations. The memory select lines should be set
simultaneously and remain set for a minimum of 20ms to guarantee that the correct
memory will be selected. However, the memory select bits may be set in sequential
manner, provided that the time delay between each bit is less than 4ms. When the
desired bit pattern has been established it should remain set for a minimum of 20ms
to guarantee that the correct memory will be selected. It may be necessary to "OR"
the momentary switches (relay contacts) to prevent incorrect program selection due to
timing errors.
ACTIVATING MEMORY PROGRAM FUNCTIONS THROUGH
THE REMOTE CONNECTOR, SELECTS THE PROGRAM AND
STARTS THE TEST WHICH IS PREPROGRAMMED INTO
THAT MEMORY
DO NOT CONNECT VOLTAGE OR CURRENT TO THE SIGNAL
INPUTS, THIS COULD RESULT IN DAMAGE TO THE
CONTROL CIRCUITRY.
MEMORY ONE – Momentarily connecting terminal 7 to 8 signals the instrument to
immediately begin the test program that is stored in memory one.
MEMORY TWO – Momentarily connecting terminal 7 to 9 signals the instrument to
immediately begin the test program that is stored in memory two.
MEMORY THREE – Momentarily connecting terminal 7 to terminals 8 and 9 signals
the instrument to immediately begin the test program that is stored in memory three.
Remote Interlock
HypotMAX is equipped with a Remote Interlock feature. Remote Interlock utilizes a
set of closed contacts to enable the instrument’
s output. If the Remote Interlock
contacts are open the output of the instrument will be disabled. Remote Interlock
could also be referred to as a remote system lockout, utilizing “fail when open” logic.
If the Remote Interlock contacts are open and the TEST button is pushed, a pop-up
message will be displayed on the screen for two seconds. The message will appear
as follows:
