Case & Valve Grounding

This equipment must be earth grounded. Use any screws on

the bottom of the ValveLink case for grounding. Order AutoMate

part no. 01-05 "Low noise, valve and case grounding package" for

an extra grounding wire attached to each individual valve ex-

tend ing back to the controller. Each of this item grounds four (4)

valves. Please order two for eight channel perfusion systems. This

item must be ordered at the same time as the valves. Connect the

ground wire from the valves to a screw on the bottom of the control-

ler case.

Digital inputs

(see previous page)

The ValveLink includes several useful features as auxiliary

'Modes.' The user alters the current mode settings by holding but-

ton #0 down while powering the ValveLink on or while pressing

and releasing the Reset button. LED #0 should begin fl ashing. Indi-

vidual modes are toggled on and off by pressing their button while

LED #0 is fl ashing. The LED associated with each button should

change from red to green, with green representing ON. All of the

modes can be used simultaneously, except numbers 1 and 2 which

cannot both be on. Press button #0 to return to normal ValveLink

operation with any modes activated.

The ValveLink cannot remember which modes are active

when powered off. Therefore, all modes are deactivated when the

ValveLink is turned off or unplugged. However, modes are main-

tained after pressing the Reset button. Hold button #0 down while

resetting the ValveLink to view and change the current mode set-

tings as described above. NOTE - Reset also closes all valves.

Mode Descriptions

Binary Demultiplexed Addressing Mode

(Valves 0-7 for two ValveLink8's)

TTL inputs 0-2 decode into a binary number 0-7

representing which valve to open. When this 3-bit number changes,

the previous valve is closed. When Mode 1 or 2 is used, TTL inputs

0-3 are used for addressing and no longer directly control valves 0-3.

Example: TTL input 0000 0101 opens valve 5 (its decimal equiv-

a lent). For ValveLink16's, ad di tion al bit 3 is used as de scribed in the

next para graph to further select bank 2.

Addressing Mode - Valves 8-15 (2nd ValveLink8)

This is the same binary decoding of bit 0-2 as Mode

#1, but bit 3 is used to select between two ValveLink8's and con-

trol up to 16 valves with a single 4-bit TTL source. Set the fi rst

ValveLink8 to Mode 1, the second to Mode 2, and connect TTL input

bits 0-3 from both ValveLinks to your digital output. Bits 0-2 decode

which valve is opened on the ValveLink selected by the fourth bit
