Electronic Instrument Installation
To install dual 100G Series Gas ERT Modules to a Honeywell Instrument Mini-Max Case
Volume Corrector using Honeywell Kit 22-1077
1. Place the Honeywell Instrument volume corrector in shutdown condition and disconnect all power from
the Mini-Max main board.
2. Remove the battery pack from the volume corrector and set it aside.
3. Remove the four screws from the main board and the board from the enclosure. Set the board aside.
4. Remove the two hex screws from the input switchboard and the switchboard from the enclosure and set it
aside. You will re-install the switchboard later.
Warning The battery pack, main board and switchboard may be damaged if left in the Honeywell
Instrument volume corrector while completing this installation.
5. Drill two 3/16-inch holes in the back of the Mini-Max enclosure as specified by the information included
in the kit. Remove any metal shavings from the enclosure.
6. Clean the 100G series remote gas modules with the alcohol wipe where you will place the corrected and
uncorrected labels (included in the kit).
Note Clean the 100G series remote gas modules with the alcohol wipe to ensure good label adhesion.
7. Mount the module for corrected pulse outputs on the left bracket mounting space. Insert three #8-32 x 1/2-
inch screws in a triangular pattern. Install the top screw so the head of the screw is approximately 1/8-inch
from the ERT mounting bracket surface. Slide the module onto the screw so the mounting lug fits securely
onto the screw. If necessary, remove the module and make any necessary adjustment to the screw depth to
ensure a secure fit. Install the two bottom screws in an alternating fashion.
8. Mount the module for uncorrected pulse outputs on the right bracket mounting space. Insert three #8-32 x
1/2-inch screws in a triangular pattern. Install the top screw so the head of the screw is approximately 1/8-
inch from the ERT mounting bracket surface. Slide the ERT module onto the screw so the mounting lug
fits securely onto the screw. If necessary, remove the module and make any necessary adjustment to the
screw depth to ensure a secure fit. Install the two bottom screws in an alternating fashion.
9. Route the module cables under the bracket edge and toward the rear of the Honeywell Instrument.
10. Mount the ERT mounting bracket (Honeywell Instrument part number 22-1077, included in the kit) onto
the Mini-Max enclosure. Place a #8 metal flat washer followed by a rubber sealing washer onto both #8-
32 x 3/8-inch screws. Align the lower threaded holes in the mounting bracket with the drilled enclosure
holes and insert a screw/washer through the enclosure housing. Screws heads must be inside the enclosure.
Tighten both screws using a screwdriver.
Note Aligning the second bracket threaded hole and drilled hole may require some manipulation of the
mounting bracket.
11. Insert the module cables (both units) through the large cable strain relief on the left rear of the instrument's
enclosure. Leave a one-half to one inch drip loop under the cable strain relief.
12. Secure three cable ties on the module cables in three places on the cables as specified by information
included in the kit.
13. Re-install the input switchboard, main board, and battery pack removed in step 2.
