Verometer No Fill Alarm Troubleshooting Steps
When an active No Fill alarm is indicated, the following steps should be taken:
1. Refer to the P&ID to ensure the correct valves are open to allow the verometer to fill.
2. Check the bulk odorant supply filter and valves for possible restriction or closure and
adjust or replace as necessary.
3. Check tubing between bulk odorant storage tank and enclosure for damage or leaks. If
tubing is crimped, bent, or damaged, by any form that could restrict flow, replace the
tubing.
4. Check the inlet pressure read on the N-400 controller screen
– ensure inlet pressure is
within 10-25 psi (0.7
–1.7 Bar). If the pressure is increasing when the transfer pump turns
on, contact YZ Technical Service.
5. If the verometer is still not filling, contact YZ Systems Technical Service.
Verometer Slow Fill Alarm Troubleshooting Steps
When an active Slow Fill alarm is indicated, the following steps should be taken:
IMPORTANT NOTE: Prior to troubleshooting a slow fill alarm, verify that the Verometer is
not in a full level position as the transfer pump commands cannot be processed if the
Verometer is full.
1. Refer to the P&ID to ensure the correct valves are fully open to allow the verometer to fill.
2. Check bulk odorant supply filter and valves for possible restriction or closure and adjust
or replace as necessary.
3. Check tubing between bulk odorant storage tank and enclosure for damage. If tubing is
crimped, bent, or damaged by any form that could restrict flow, replace the tubing.
4. Check tubing between the bulk odorant storage tank and the blanket gas connection on
the back of the cabinet. If tubing is crimped, bent, or damaged by any form that could
restrict flow, replace the tubing. Disconnect the blanket gas line and check for misdirected
odorant and drain if discovered.
Verometer Leakage Alarm Troubleshooting Steps
When an active Leakage alarm is indicated, the following steps should be taken:
1. Inspect the system for any obvious leaks and repair as necessary.
2. If the Leakage alarm occurs during purging of the system or the packing of the lines with
odorant on a new system, a manual refill of the verometer will be required and this will
clear the alarm.
3. Verify the odorant supply pressure is between 10 - 25 psi (.68 - 1.72 Bar)
